10 Trinity Square, Grade II* listed office building in Tower Hill, London, United Kingdom.
The Portland limestone structure features Corinthian columns and a dome, with 10 stories of office space overlooking the River Thames near Tower Bridge.
Opened in 1922 as the Port of London Authority headquarters, the building suffered damage during World War II, leading to reconstruction of its central rotunda.
The building's restored boardroom hosted the first United Nations General Assembly meeting in 1946, marking a key moment in international relations.
The building now functions as Four Seasons Hotel with 100 rooms and private residences, accessible via Tower Hill underground station.
Archaeological excavations during renovations uncovered remnants of Roman London and a 17th-century Christopher Wren building beneath the foundation.
