This was the West Pier in Brighton, on the south coast of England. The pier was erected in 1866 and remained largely unaltered after the addition of a concert hall in 1916. The disused pier partially collapsed in 2002 and a mysterious fire destroyed much of the remaining structure in 2003. In this photo, which shows the state of the pier in the mid- to late 1990s, you can see the massive flock of starlings which used to take to the skies and swarm, cloud-like, above the end of the pier at sunset every day, before settling for the night inside the abandoned structure. You can read more of the history of the pier here.
