Port of London Authority Building, London 1971

The Port of London Authority (PLA) Building in Trinity Square, London, is a distinguished and historically significant building that once served as the headquarters for the organisation responsible for overseeing the Port of London.

Overview:

• Location: Trinity Square, near Tower Hill, in the City of London, just a short walk from the Tower of London and Tower Bridge.

• Built: 1912–1922

• Architect: Sir Edwin Cooper

• Style: Edwardian Baroque / Beaux-Arts

• Status: Grade II* listed building

History and Features:

The PLA Building was designed to reflect the wealth and importance of the Port of London during the early 20th century, when it was one of the busiest ports in the world. Constructed over a decade, the building is a grand expression of imperial confidence, featuring:

• A striking Portland stone façade

• Ornamental sculptures symbolising commerce and navigation

• A central tower with maritime motifs

• Lavish interiors with wood panelling, marble, and decorative plasterwork

The Port of London Authority, formed in 1908, was tasked with modernising and managing the tidal Thames from Teddington to the North Sea. This building served as its headquarters for many decades.

Modern Use:

Today, the former PLA Building is no longer used by the Port of London Authority (which moved out in the 1980s). It has since been:

• Renovated and repurposed as a luxury hotel known as Four Seasons Hotel London at Ten Trinity Square

• Home to private residences and club spaces

• Still retaining many original architectural features

Its prominent location, opposite Trinity House and overlooking Trinity Square Gardens, makes it one of the standout buildings in this historic part of the City of London.
