The Smithsonian Institution Building is constructed of Seneca red sandstone in the faux Norman style (a 12th-century combination of late Romanesque and early Gothic motifs; built in the Gothic and Romanesque revival styles) and is nicknamed The Castle. It was designated a National Historic Landmark in 1965. A statue of Joseph Henry is displayed in front of the building.
The Castle was the first Smithsonian building, designed by architect James Renwick, Jr. The building committee held a nationwide design competition in 1846 and selected Renwick's design by a unanimous vote.
The construction began in 1847. The East Wing was completed in 1849 and occupied by Secretary Joseph Henry and his family. The West Wing was completed later the same year. A structural collapse in 1850 of partly completed work raised questions of workmanship and resulted in a change to fireproof construction. The Castle's exterior was completed in 1852; Renwick's work was completed and he withdrew from further participation. Cameron continued the interior work, which he completed in 1855.
Despite the upgraded fireproof construction, a fire in 1865 caused extensive damage to the upper floor of the building, destroying the correspondence of James Smithson, Henry's papers, two hundred oil paintings of American Indians by John Mix Stanley, the Regent's Room and the lecture hall, and the contents of the public libraries of Alexandria, Virginia and Beaufort, South Carolina, confiscated by Union forces during the American Civil War. The ensuing renovation was undertaken by local Washington architect Adolf Cluss in 1865-67. Further fireproofing work ensued in 1883, also by Cluss, who by this time had designed the neighboring Arts and Industries Building. A third and fourth floor were added to the East Wing, and a third floor to the West Wing.
The Smithsonian Castle houses the administrative offices of the Smithsonian. The main Smithsonian visitor center is also located here, with interactive displays and maps. Computers electronically answer most common questions. A crypt just inside the north entrance houses the tomb of James Smithson.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
