Joseph Grimaldi Park in Islington is, perhaps unsurprisingly, named after Joseph Grimaldi — a popular pantomime clown during the early 19th century. He is buried here, but the site is far from solemn. Seek out the public artwork consisting of bronze floor tiles and you'll encounter a marvellous, musical surprise.
Joseph Grimaldi Park is located at 11 Collier St (off Pentonville Road), N1 9JU.
