Explore London's very own Sistine Chapel close up
You may already be aware that the Old Royal Naval College in Greenwich has an impressive Painted Hall. In fact, it's so impressive, it's often referred to as 'the Sistine Chapel of the UK'.
You can now get up-close to this sky-high artwork on a new tour. Ascend 60 feet and see the paintings from a special observation deck, for the first time in over half a century.
This is all part of a major conservation project for the Painted Hall — maybe you'll be inspired to sponsor a square foot of this masterpiece. Book your tickets for the tour here.
Art review: Picasso the matador
Picasso was obsessed with bullfights and this exhibition builds on that. The collection of paintings, sculpture and drawings focuses on bullfights, matadors and the myth of the minotaur. Picasso captures the unbridled energy of these scenes in powerful masculine paintings. Gagosian Gallery has gone all out here and transformed the gallery into a museum-esque show that wouldn't feel out of place in, say, the Royal Academy — it's a truly spectacular exhibition. Picasso: Minotaurs and Matadors at Gagosian Gallery, 20 Grosvenor Hill, W1K 3QD, until 25 August, free ★★★★★ (Tuesday-Saturday) Tabish Khan
Art review: slow moving art
George Rickey's sculptures slowly flex, rotate and transform. Their slow, moving grace had us transfixed. He was a contemporary of the more famous Alexander Calder, but his works are just as effective. George Rickey: Sculpture from the Estate at Marlborough Fine Art, 6 Albemarle Street, W1S 4BY, until 20 May, free ★★★★☆ (Monday-Saturday) Tabish Khan
Good cause for the day
CATFEST: Slightly misleadingly named, the third edition of Catfest has absolutely nothing to do with furry felines.

The first night is all about dancing, later on during the weekend there'll be a vintage market, craft fair and a screening of Hidden Figures. Catford Constitutional Club, free (donations encouraged), just turn up, 28-30 April
