Wallblake House is a heritage plantation house and museum annex in The Valley, Anguilla in the northeastern Caribbean. Built in 1787 by Will Blake, a sugar planter, it is stated to be the oldest structure on the island. Although gutted by the French in the late 1790s, it was rebuilt by the British and today has been fully restored, with its kitchen complex, stables and slave quarters intact. A church in the vicinity contains a stone fascia with open-air side walls and a ceiling, which is the form of a hull of a ship.
