Cullands Grove, also known as Cannon's, was a country house and estate in Southgate, Middlesex. It was built on an area of woodland formerly known as Gullands Grove. Cullands Grove was known for the lavish banquets held there by Sir William Curtis 1st Baronet of Cullands Grove and after his death in 1829 it took a week to auction the contents of the house and estate which included 370 dozen bottles of wine. Around 1840, the estate was merged into the Grovelands estate and the house demolished.
