The historic former headquarters of the Port of London Authority has been turned into a five-star hotel with 100 rooms and suites, plus event spaces for up to 200 guests.
The Four Seasons Hotel London at Ten Trinity Square sits just by Tower Hill station. It houses three meeting rooms and two ballrooms, including the formal, wood-panelled UN Ballroom.
Private dining for up to 14 is available in its Asian restaurant and also in La Dame de Pic, a fine diner from the only female French chef with three Michelin stars.
