Overview

Your chance to explore the history and architectural highlights of Carlton House Terrace, the home of the UK’s national academy of science.

On 17 and 18 September 2022, Open House, the largest annual festival of architecture and design, returns to the capital. Over the weekend, visitors are invited to discover the secrets of the Grade I listed, Nash-designed town houses that are currently home to the oldest scientific academy in continuous existence.

Uncover countless treasures behind the doors of 6-9 Carlton House Terrace, including portraits of Royal Society Fellows dating back to the 1600s, an ornate mother-of-pearl inlay ceiling, and features from the building's time as the pre-WWII German Embassy.

See this 19th century building by joining one of our free guided tours hosted by staff from the Royal Society’s library team or explore at your own pace with our free self-guided tour, available to collect on the day. Please note, places are limited for our free guided tours and you must book your spot at the building on the day of the tour.

What is Open House?

Open House is a simple but powerful concept: hundreds of great buildings of all types and periods open up their doors to all, completely without charge. 

This unique opportunity to access and understand architecture is a chance to look at everyday buildings anew and communicates the value of a well-designed city to everybody who uses it. For more information visit the Open House website.
