The Line is a public art trail in London, opened in 2015, that very roughly follows the path of the Greenwich meridian as it crosses the River Thames.[1][2] It consists of a set of artworks positioned on a 7.7-kilometre (4.8 mi) walking route starting at the London Stadium, passing down the Lea Valley, crossing the Thames via the London Cable Car, and ending at The O2 in Greenwich.[3] The trail includes works by Anthony Gormley and Tracey Emin.[4]
