Victorian illustration to download showing stonemasons at work during the re-building of the Houses of Parliament, 1848. They carve roof bosses for the Central Lobby of the House of Commons. Timber scaffolding lashed together with rope supports plank platforms. The masons, 75ft above the floor, work on the bosses which adorn the ribs of the vaulted roof. The old Palace of Westminster was largely destroyed by fire in 1834. Re-building began in 1840, and lasted for 30 years. The architect was Charles Barry, assisted by Augustus Pugin, who designed the interiors.
