Summer in the Square; Portman Square Garden, Marylebone; Tuesday 7th July – Sunday 12th July 2026, 12pm to 8pm daily; FREE
For six days only, the heavy iron gates of Marylebone’s private Portman Square Garden are swinging open to the public for the 12th annual Summer in the Square. This is a quintessential British summer garden party, completely free to enter, and right in the heart of London W1.
A rare opportunity to step inside an enchanting, normally locked residents’ garden, transformed with deck chairs, sun-dappled lawns, and a relaxed village-like atmosphere. Avoid the chaotic queues and watch the high-stakes final week of Wimbledon streamed live on a giant screen, surrounded by elegant greenery.
Sip bespoke cocktails and chilled spritzes from the exclusive Home House garden bar, while sampling global flavours from the Street Food Village and rotating star chefs at The Guest Kitchen. Recharge with complimentary expert-led yoga, breathwork, and mindfulness sessions at the Wellness Den, or book into creative art workshops.
