The   Hazelwood   Heritage   Society   has   for   many   years   worked,   and   will   continue   to   do   so,   to   achieve recognition   for      Hazelwood   House,   highlighting   the   importance   of   Hazelwood   as   a   part   of   our   built heritage in the North West. The   German   architect   Richard   Cassells   designed   and   supervised   the   building   of   the   great   house   in 1731.   It   was   to   be   the   first   Palladian   Villa   designed   by   him   to   be   seen   in   Ireland.   The   design   of Hazelwood   became   the   prototype   for   other   great   houses   built   to   his   design   here,   including   Leinster House, Powerscourt House and Bellinter House.
The Wynnes of Hazelwood House                                  The   Hazelwood   Wynnes   originated   from   Wales   claiming   descent   from   a   distinguished chieftain   of   the   12th   century   in   Merionetshire.   The   first   of   the   family   to   settle   in   Ireland   was   Owen Wynne   who   received   a   grant   of   lands   in   and   around   Lurganboy,   and   was   succeeded   in   1670   by   his eldest   son,   Capt.   James   Wynne,   who   fought   on   the   Williamite   side   at   the   siege   of   Derry,   later   at   the Boyne. The   Wynne   family   occupied   Hazelwood   House   for   three   hundred   years,   during   which   time   all the head's of the Wynne household, with only one exception, bore the name of Owen Wynne.

Hazelwood House An 18th-c Palladian style country house  located in a 70 acre demesne in Calry parish   2 miles  south-east of Sligo town in north-west Ireland.  It consists of a 5-bay by 3-bay main block in 3-storeys with 2-storey wings on either side connected to the main block by single-  storey quadrants. The building is constructed of limestone ashlar with  slate roofs. The house, which originally stood in a wooded estate of 15,000 acres, was designed by architect Richard Cassels c.1730 for Lt-Gen. Owen Wynne, a descendant of the Welsh Wynne family from Merioneth. On his death in 1737, the estate passed to his nephew, also Owen Wynne (1686- 1755) who was an Army officer. He was succeeded by his son, a third Owen, who was High Sheriff of Sligo for 1723 and 1745.
