Druim Moir Castle

Druim Moir, also known as the Houston Estate Historic District, is a significant historic site located in the Chestnut Hill neighborhood of Philadelphia, Pennsylvania. The name translates to Great Ridge in Scottish Gaelic, reflecting the estate's prominent position bounded by Fairmount Park and local streets. The centerpiece of this forty-seven-and-a-half-acre district is Druim Moir Castle, constructed between 1885 and 1886 for Henry H. Houston. Designed by the architectural firm G. W. and W. D. Hewitt, the structure exemplifies a Picturesque Eclectic style that blends Shingle Style and Romanesque elements. Built at a cost exceeding $115,000, the original thirty-room residence was the largest home in its vicinity, crafted from local Wissahickon schist with Eastern granite trim and a slate roof.

The estate holds considerable historical significance due to its association with Henry Houston, who was the largest landowner in Philadelphia during the 1880s. Houston amassed his fortune through roles with the Pennsylvania Railroad and ventures in gold mining, shipping, and petroleum. He developed the surrounding Wissahickon Heights neighborhood, which includes over eighty homes. The castle's interior was renowned for its extensive use of diverse woods, including oak, mahogany, butternut walnut, and cypress, designated for specific rooms to create distinct atmospheres. The district also includes Brinkwood, a Shingle-style residence built as a wedding gift for Houston's son in 1887.

Over time, the property has undergone notable changes that reflect its evolving use and preservation status. In the early twentieth century, architect Robert Rodes McGoodwin redesigned the gardens for Samuel F. Houston. Significant structural alterations occurred in 1952 when the top story and towers were removed from the main castle. Despite these modifications, the district was added to the National Register of Historic Places in 1979 and serves as a contributing property to the broader Chestnut Hill National Historic District. Today, it stands as a preserved testament to late nineteenth-century industrial wealth and architectural innovation in the region.
