A view from the River Thames in London on a bright, cloudy day. In the foreground, the murky water reflects the sky. Southwark Bridge spans the middle ground, with its green arches and stone piers. To the right, the glass-clad, needle-like spire of The Shard towers over the surrounding modern office buildings. In the far distance, the iconic towers of Tower Bridge are visible against a horizon of blue sky and puffy white clouds.
