The Abbey Drain was rediscovered just over twenty years ago in the early1990’s. Prior to that it was last unearthed in the 1800’s.
As part of the Doors Open weekends of 2009, 2010 and 2011 work was undertaken to uncover more about the drain. The archaeological digs which took place in the week leading up to Doors Open weekends, carried out by Guard Archaeology Ltd and the Renfrewshire Local History Forum.
The 2009 and 2010 archaleological digs were aimed at discovering more about the outside of the drain whilst in 2011 the main aim of the dig was to find out why the drain did not run in a straight line.
