Open House Festival 2026

Explore some of Piccadilly & Jermyn Street’s most fascinating buildings and discover the stories behind the West End neighbourhood.

Saturday 12 September – Sunday 20 September 2026

This weekend, Open House Festival returns for nine days of discovery across London. This year, HOLBA’s Art of London is delighted to partner with the festival and bring the first-ever Piccadilly & Jermyn Street neighbourhood to the programme.

From historic societies and scientific institutions to iconic businesses and places of worship, Open House offers a chance to step inside buildings you may have passed countless times and discover a different side of the West End.

The Piccadilly & Jermyn Street area is home to an extraordinary mix of institutions, businesses and cultural landmarks, many of which have played a part in London’s history for generations. Bringing them together as part of Open House is a fantastic way to showcase the character of the neighbourhood and invite people to see this characterful part of the West End with fresh eyes.
