London as August Begins: Unmissable Last-Minute Deals and Brand-New Openings This Friday

August is knocking on the door! This Friday (July 31, 2026), London’s art calendar experiences a double turning point: On one hand, we say goodbye to the Oliver Beer exhibition in Mayfair, which transforms sound frequencies into paint, while on the other hand, a jarring exhibition focusing on the relationship between childhood and war opens to the public at the Imperial War Museum. Over the weekend, the final whistle blows for the botanical feast at Saatchi.

CLOSING THIS FRIDAY — Oliver Beer “The Sky in the Cave” / Thaddaeus Ropac

July 31, 2026 (Friday) | Free Admission

Giant canvases in the heart of Mayfair, primitive echoes in the Dordogne caves, and special sound recordings made with Rufus Wainwright… Friday is the last day for this fascinating experience that transforms sound into color. This free-to-visit exhibition is a great stop for Friday afternoon.

• Venue: Ely House, 37 Dover Street, W1S 4NJ

OPENING THIS FRIDAY — IWM “Childhood in War” / Imperial War Museum London

July 31, 2026 (Friday) – February 28, 2027 | Free Admission

The UK’s first major museum exhibition dedicated to the theme of war and childhood. From 1914 to the present; a deeply jarring and human narrative shaped around play, school, family, and shelter. It will remain open for seven months; however, the excitement of being among the first to enter on opening day is something else entirely.

• Venue: Lambeth Road, SE1 6HZ

CLOSING THIS WEEKEND — RHS Botanical Art & Photography / Saatchi Gallery

August 2, 2026 (Sunday) | Prices starting from £6 / Free for RHS and Saatchi members

Bringing together delicate works by botanical artists and photographers from around the world, the show has entered its final weekend. Saturday and Sunday are the last two days!

BEFORE CLOSING THIS WEEK — Kenjiro Okazaki / Pace London

August 7, 2026 (Friday, next week) | Free Admission

With its extraordinary title stretching from the infinite loop of the Beatles to Aristotelian philosophy (“Never could be any other way — anagnorisis”), this first UK solo exhibition by the Japanese artist ends next week. With 9 days left until closing, be sure to add it to your Mayfair route.

NO-26 Editor’s Note

London is offering both the excitement of new openings and the nostalgia of bid farewells at the same time this week. Friday, July 31, is one of the busiest points on the 2026 calendar: On one side, sound transforms into color on canvas, while on the other, the history of war unfolds through the eyes of children.
