Clockmaker John Harrison's Nostell Priory honour

More than 2,000 ticking clocks have gone on display in an art installation as British Summer Time (BST) begins.

Set up at Nostell Priory, near Wakefield, it has been created to celebrate the life of clockmaker and inventor of the marine chronometer John Harrison.

The Harrison's Garden installation by artist Luke Jerram fills an entire room.
