Stone horsemen invade River Thames

It's not uncommon to see huge art installations on River Thames: a giant fiberglass sperm whale, a floating house, a massive wooden hippo. If you happen to be in London, head down to Nine Elms, on the south bank of the waterway, any day this month, and — if it's a low tide — you'll see a group of stone horsemen by world-renowned underwater sculptor Jason deCaires Taylor, rising above the riverside beach.

The artwork, titled The Rising Tide, is part of the Totally Thames arts festival and is the first of its kind to be installed in the famed river. Four three-meter tall working horses with riders are shown — two of the riders are businessmen and two are children — though horse heads have been replaced with oil pumps. The sculptures are on display until the end of September.
