10 Trinity Square, Grade II* listed office building in Tower Hill, London, United Kingdom.
10 Trinity Square is a limestone office building distinguished by its Corinthian columns, ornate dome, and 10 stories of interior space with views toward the Thames near Tower Bridge. It now operates as a hotel with private residences, making its grand public spaces and rooms accessible to visitors.
Built in 1922 as headquarters for the Port of London Authority, the building served as an administrative hub for the city's shipping operations. World War II bombing damaged it significantly, but the central rotunda was carefully rebuilt to restore its iconic form.
The restored boardroom once hosted the first United Nations General Assembly meeting, making it a landmark in the story of international cooperation. Visitors can sense this diplomatic heritage in the building's formal spaces and grand design.
The building sits directly above Tower Hill underground station, making it easy to reach on foot from central London. Visitors can explore the hotel's public areas and enjoy views of the Thames and surrounding landmarks from the upper floors.
Archaeological digs during renovation work revealed remains of Roman London and a 17th-century Christopher Wren structure buried beneath the building's foundation. These hidden layers tell the story of continuous occupation and importance at this riverside location.
