Having its own unique place in the history of American architecture, Hidden Valley Castle, another name of Cornwall Castle, is hidden amid the green hills of Connecticut in one of the most beautiful counties of that state – Litchfield County. This magnificent glass palace is a reminder of the early 20 th century ambition, European skills and the desire of an extraordinary women who took a chance to make medieval grandeur appear in the New England countryside.
The Visionary Behind the Castle: Charlotte Bronson Hunnewell Martin
In the case of Hidden Valley Castle, it all started with Charlotte Bronson Hunnewell Martin, a socialite and a very rich lady who had architectural bigger plans than normal summer houses. To Charlotte, ground-breaking real estate development was not a new thing because she had already left her mark on the Upper East Side of Manhattan several years before with a historic urban project that would shape the city planning in the urban area over the next several generations.
Prior to starting her Connecticut castle construction process, Charlotte was already showing off her good sense of innovative living places by acquiring twenty brownstones in Manhattan. Instead of going ahead as two different properties, she had something new at that time, a truly revolutionary idea; to transform them into a series of extremely chic townhouses set around a striking central Italian style garden courtyard. This was a development called the Turtle Bay Gardens, and was one of the most prestigious addresses in Manhattan at the time displaying Charlotte was capable of integrating the European visual styles and the American pragmatism.
Turtle Bay Gardens was a success and Charlotte had delivered on her reputation of not being satisfied with architecture and made it clear that she was about to make an even greater contribution to architecture. Soon, her dream of a summer holiday destination in the Litchfield Hills of Connecticut would turn out to be much more than what people could have expected.
Dr. Walton Martin: The Supporting Partner
Charlotte’s husband, Dr. Walton Martin, played a crucial supporting role in bringing the castle vision to life. As a successful physician, Dr. Martin not only provided the financial backing necessary for such an ambitious undertaking but also brought his methodical approach to the project’s execution. His involvement ensured that the castle would be built to the highest standards, incorporating both aesthetic beauty and practical functionality.
Dr. Martin’s commitment to the project was evident in his willingness to import specialized materials from Europe and coordinate the efforts of one hundred skilled workers over the five-year construction period. His partnership with Charlotte created the perfect foundation for realizing their shared dream of a Connecticut castle.
The Architectural Genius: Edward Clarence Dean
The architect that Martins employed also made the difference in the castle. Edward Clarence Dean, already having showed his powers in the reinvention of the Charlotte Turtle Bay Gardens project had an absolute experience in adopting European architecture to American designs. His development of Turtle Bay Gardens showed Dean capable of producing homogenous, discreet spaces that entertained historical precedent in a contemporary way.
In the case of Cornwall Castle project, Dean was inspired by the medieval fortification of Europe but introduced the contemporary facilities and construction elements. His design approach was centered geared towards the truth of materials and craftsmanship and makes the castle a comfortable modern house. The detail of work and the interior devotion to historical truth would show itself in every stone of the structure, every archway, and tower that was completed by the architect.
The cooperation of Dean with Martins was not some kind of a usual attitude of a client to an architect. It was an encounter of minds, who had a common passion to create something really great. The fact that the architect had already created a success with Turtle Bay Gardens made the Martins believe that their idea can be turned into reality and Dean was happy to work on this project of grand proportions and ambitions.
The Five-Year Construction Epic (1916-1921)
Construction of a Hidden Valley Castle is one of the greatest examples of ambition in any kind of the 1900 private building. The construction phase started in 1916 and lasted five years, which was also related to the complexity of the project and excellence of the Martins. This was not just the matter of a big house construction, but the matter of the real medieval atmosphere in Connecticut country.
European Material Imports
The move taken by Dr. Martin to have materials shipped in directly into Europe, showed that the project had the interest of authenticity in mind. The stone, also used, was quarried at places that reflect the medieval construction methods and this means that by the time the castle was to be constructed, it would have the same weathered beauty and structural integrity of the castles in Europe. Such imported materials were:
Blocks of limestone, quarried long before to escape the use of the medieval builders, and to give antiquity to every wall, and foundation. Hand-turned and hand-forged iron work by European blacksmiths using traditional metal shaping skills so as to produce hardware, fixtures and decoration items that were in accordance with the specifications of the period. Specialist roof coverings such as slate slate roofing tiles and lead guttering systems which copied medieval water management techniques but kept them with current functionality.
Importation was a delicate coordination that had to be done with overseas suppliers and lines, and this made what was already a massive project even more complicated. The packaging of each shipment was to be well catalogued and stored to enable materials to be delivered in the right condition and at the right time based on construction schedule.
The Hundred-Worker Construction Team
Assembling a workforce capable of executing such a specialized project required recruiting craftsmen with particular skills. The one hundred workers brought together for the castle’s construction represented a diverse collection of talents, including stonemasons familiar with medieval building techniques, carpenters skilled in traditional joinery methods, and metalworkers capable of creating authentic period hardware.
Many of these craftsmen were European immigrants who brought Old World building traditions to the Connecticut hillside. Their expertise ensured that construction methods remained faithful to medieval practices while incorporating necessary modern safety standards and structural requirements. The collaboration between these skilled artisans and American workers created a unique learning environment where traditional techniques were preserved and passed on to a new generation.
The five-year timeline allowed for the careful, methodical construction that such detailed work required. Rather than rushing to completion, the extended schedule ensured that each element of the castle received proper attention, from foundation work to final decorative details.
Architectural Features and Design Elements
Hidden Valley Castle stands as a masterpiece of medieval revival architecture, incorporating authentic design elements that transport visitors back to the age of knights and nobility. The structure’s design reflects careful study of European castle architecture, with particular attention paid to both defensive features and residential comfort.
Defensive Architecture Meets Residential Comfort
The castle’s exterior presents classic medieval defensive features including thick stone walls, strategically placed windows, and imposing towers that suggest the structure’s ability to withstand siege warfare. However, these defensive elements serve primarily aesthetic purposes, as the castle was designed from the beginning as a luxurious residence rather than a functional fortress.
Interior spaces blend medieval grandeur with early 20th-century comfort, featuring high vaulted ceilings, massive stone fireplaces, and intricate woodwork alongside modern plumbing, electrical systems, and heating infrastructure. This combination creates an atmosphere of historical authenticity without sacrificing contemporary convenience.
Stone Construction and Craftsmanship
The castle’s stonework represents some of the finest examples of traditional masonry techniques applied to American residential construction. Each stone was carefully selected and placed according to medieval building practices, with attention paid to both structural integrity and aesthetic appeal. The walls feature the thickness and construction methods of authentic medieval fortifications, providing excellent insulation and soundproofing qualities that enhance the building’s functionality as a residence.
Decorative stone carving throughout the structure includes heraldic symbols, floral motifs, and geometric patterns that reflect medieval artistic traditions. These carved elements were created by skilled artisans who understood the symbolic meanings and aesthetic principles of medieval decoration, ensuring that every detail contributed to the castle’s authentic atmosphere.
The Connecticut Setting: Litchfield Hills Context
The choice of Connecticut’s Litchfield Hills as the castle’s location proved inspired, as the region’s rolling topography and dense forests create a natural setting reminiscent of the European countryside where medieval castles originally stood. The area’s elevation changes and scenic vistas provide dramatic backdrops that enhance the castle’s imposing presence while offering panoramic views of the surrounding landscape.
Natural Integration with the Landscape
Hidden Valley Castle was positioned to take advantage of the site’s natural features, with the structure appearing to emerge organically from the hillside rather than imposing itself upon the landscape. This integration reflects both medieval castle-building practices, where defensive structures utilized natural terrain features, and early 20th-century American landscape architecture principles that emphasized harmony between buildings and their natural settings.
The castle’s grounds were carefully planned to include formal gardens, woodland paths, and open meadows that provide varied outdoor experiences while maintaining the property’s secluded character. These landscape elements serve both practical and aesthetic purposes, creating natural boundaries while enhancing the castle’s fairy-tale appearance.
