Work was also progressing on the northern half of the West Wing (The Egyptian Sculpture Gallery) 1826–1831, with Montagu House demolished in 1842 to make room for the final part of the West Wing, completed in 1846, and the South Wing with its great colonnade, initiated in 1843 and completed in 1847, when the Front Hall and Great Staircase were opened to the public.[53] The museum is faced with Portland stone, but the perimeter walls and other parts of the building were built using Haytor granite from Dartmoor in South Devon, transported via the unique Haytor Granite Tramway.[54] ./cache/en-wikipedia-org-2747.html ./txt/en-wikipedia-org-2747.txt
