When Cogges Farm Museum in Witney was threatened with closure a few years ago we stepped in with the offer of building their website for them.  It was the beginning of many good things, but, in particular, working closely with the Cogges team to understand their needs helped us develop our technology for other clients.
 
Cogges is now run by a Trust which works hard to make this unique place in Witney work for the community.  They have an extensive newsletter (all driven by Drupal), lots of events, volunteers and more.  We've continued to develop the site for them and joined forces with another local Drupal developer to continue to support their needs.
 
Their site is full of wonderful photographs taken by Gary Ombler, a well known photographer, and the design of the site needed to make the most of these.  This is still very much part of the charm and a great showcase for this special museum.
