Trinity Square lies to the north of the Tower of London.
Trinity Square Gardens has a memorial pavilion dating from the First World War, designed by Sir Edwin Lutyens, and a garden from the Second World War. These commemorate the 24 000 members of the Merchant Navy and Fishing Fleet who rest in the sea without a traditional grave. Trinity Square Gardens is historically significant as the location where 125 individuals were publicly executed, marked by a plaque.
Since 1793, the Corporation of Trinity House has been based here. Following damage in the Blitz, the building underwent reconstruction and extension. Notably, Number 10 serves as the former Port of London Authority (PLA) Headquarters, designed by Sir Edwin Cooper between 1912 and 1922.
