The goal of the project is to capture images of fields around Belcarra, Mayo (https://en.wikipedia.org/wiki/Belcarra,_County_Mayo) in the evening after a hot day to see if any buried stonework appears indicating where Belcarra Castle was.

I first heard of the castle in Anne Chamber's excellent book Chieftain to Knight (http://www.amazon.com/Chieftain-Knight-Tibbott-1567-1629-Viscount/dp/0863270085)
