The Strand Campus is the founding campus of King's College London and is located on the Strand in the City of Westminster, adjacent to Somerset House and continuing its frontage along the River Thames. The original campus comprises the Grade I listed King's Building of 1831 designed by Sir Robert Smirke, and the college chapel, redesigned in 1864 by Sir George Gilbert Scott with the subsequent purchase of much of adjacent Surrey Street since the Second World War and the 1972 Strand Building. The Macadam Building of 1975 previously housed the Strand Campus Students' Union and is named after King's alumnus Sir Ivison Macadam, first President of the National Union of Students.
