Scattered around the Newarke Houses Museum are the ruins of Leicester's medieval castle, where Richard III spent his final days before the Battle of Bosworth. The most impressive chunk of masonry is the monumental gateway known as the Magazine, once a storehouse for cannonballs and gunpowder. Clad in Georgian brickwork, the 12th-century Great Hall stands behind a 15th-century gate near the church of St Mary de Castro, where Geoffrey Chaucer was married in 1336. The hall was closed at the time of writing due to structural damage; contact the tourist office for more details.
