The "See No Evil" arts project (which is the biggest street art exhibition in the world) recently opened in Nelson Street, Bristol. Street artists from all over the world contributed to this permanent exhibition.
Although this is probably not to everybody's taste, I am in favour of projects like this which breathes new life into run down areas of cities. There has definitely been an increase of visitors to the area and there have been enquires to open up market stalls there. All of this can only mean a new lease of life to a previously neglected part of Bristol.
More details on this project can be found on the See No Evil website and more photos can be seen on my Picasa page.
