About this pick

7 iconic London buildings you’ll be able to access for free in Open House 2026 is one of our hand-picked Events finds for London. From the BT Tower to Zaha Hadid’s archives, these are the coolest places taking part in the festival this year.

Why London? London is a vast, layered world city where royal history, endless neighborhoods, green parks and global food sit side by side. The city is known for royal landmarks, free world-class museums, West End theatre and markets.

Good to know: May–September for parks and long evenings; December is festive but cold and dark early. The Tube and buses cover everything with a contactless tap; central areas reward walking.
