Bishop’s Palace, also known as Gresham’s Castle, is a Victorian-era mansion completed in 1892 that serves as a prime example of stone architecture in Galveston. The house was commissioned by Colonel Walter Gresham and designed by architect Nicholas Clayton. It survived the Great Galveston Hurricane of 1900 largely intact, serving as a refuge for many islanders during the storm. The building features massive granite, limestone, and sandstone construction with intricate ironwork and imported marble interiors. It was purchased by the Roman Catholic Diocese of Galveston-Houston in 1923 and served as the residence for the bishop until 1963. The structure is currently owned and maintained by the Galveston Historical Foundation. Visitors can tour the interior, which contains original furnishings, stained glass, and elaborate woodwork. It is designated as a National Historic Landmark. The property occupies a prominent site within the East End Historic District.
