The buildings and gardens of Cadogan Place were laid out by Henry Holland from 1777 with the ‘north’ garden formed by Humphry Repton in 1806 with hollows, hillocks and gently winding paths.
WW2 saw railings removed to contribute the war effort with part of the garden requisitioned to host a barrage balloon in 1939. In May 1942 the entire garden was taken over by the War Office to station tanks, anti-aircraft guns and troops.
The garden was re-landscaped in the 1970s when an underground car park was built beneath. The now shallow soil presents interesting horticultural challenges and opportunities. Some particularly unusual trees are grown here, including a Brazilian pepper tree (Schinus molle) and a chinaberry tree (Melia azedarach).
