British Museum (general admission)

The British Museum unfolds from Foster’s tessellated courtyard—light washing the Greek pediments before you dive toward Egypt, Assyria, and the Enlightenment galleries. Expect weekend density around the Rosetta case; shoulder seasons reward slower reading of vitrines. Book timed slots on the museum’s own website when visitor caps apply; Saturdays stack deepest in the Egyptian rooms. Donation boxes anchor every hall, but the architecture alone justifies repeated loops on rainy London days.
