Open House Weekend

Last Updated on 12/08/2025

Open House is an exciting, free festival that showcases London’s architecture, engineering, and urban landscape. As the world’s largest architecture festival, it offers a unique opportunity to explore the city’s hidden gems. From grand Livery Halls to sleek modern skyscrapers, this event opens doors to buildings that are typically closed to the public, and provides a rare glimpse into London’s rich architectural heritage.

Although the festival takes place over a fortnight, Apothecaries’ Hall will be open for just one day. Previously we have had over 1000 visitors, so expect queues. Inside, volunteers will be stationed throughout the building, ready to share fascinating insights about the history of the rooms, paintings, and treasures.

It’s a perfect opportunity to show the Hall to your friends, and to delve into the architectural beauty and heritage that makes London and the City so special.
