St. Patrick's Chapel was the first wholly Christian church in Motherwell. It was demolished in the 18th century and some of the stonework was used to build the family mausoleum and the garden wall at Dalzell House. Some of the gravestones date back to this period and the dog's cemetery clearly reflects the Hamilton's fondness of their pets which they wished to be buried close by. Adjacent to the chapel is St. Patrick's well, a spring renowned through the centuries as having healing properties. The Victorian well head was rebuilt in the 1990's. In front of the mausoleum near the well stands a stone built summerhouse known as Lord Gavin's Temple. Lord Gavin Hamilton was often to be found reading in this quiet spot that overlooked his beloved wife's grave.
