This unusual structure is John Shaw-Rimington's artistic adaptation of a SheepFold, which he has nicknamed a SheepShear.   The original SheepFold concept was "sheared" along the diameter into two curved C walls facing each other.   It incorporates a slim gothic arch entrance way into the structure (with provision for a second arch). 

Stone benches, integrated into the interior walls, give a place to sit and reflect while perhaps enjoying a glass of wine.

The view opens onto the pond, where kingfishers frequently put on a show, accompanied (in the early spring) by the cacophony of the bullfrogs.  Deer visit frequently, as do Canada Geese and much other wildlife.

In the future, a second arch will be constructed to finish the other entrance.
