Title:
Victoria_and_Albert_Museum

Context:
Continuing the style of the earlier buildings, various designers were responsible for the decoration, the terracotta embellishments were again the work of Godfrey Sykes, although sgraffito was used to decorate the east side of the building designed by F. W. Moody, a final embellishment were the wrought iron gates made as late as 1885 designed by Starkie Gardner, these lead to a passage through the building. Scott also designed the two Cast Courts 1870–73 to the southeast of the garden (the site of the "Brompton Boilers"), these vast spaces have ceilings 70 feet (21 m) in height to accommodate the plaster casts of parts of famous buildings, including Trajan's Column (in two separate pieces). The final part of the museum designed by Scott was the Art Library and what is now the sculpture gallery on the south side of the garden, built 1877–83, the exterior mosaic panels in the parapet were designed by Reuben Townroe who also designed the plaster work in the library, Sir John Taylor designed the book shelves and cases, also this was the first part of the museum to have electric lighting. This completed the northern half of the site, creating a quadrangle with the garden at its centre, but left the museum without a proper façade. In 1890 the government launched a competition to design new buildings for the museum, with architect Alfred Waterhouse as one of the judges; this would give the museum a new imposing front entrance.

Question:
Where is the sculpture gallery now located?
