Lecale
Lecale , is the name of a peninsula and several different historical territorial divisions all located in the east of modern-day County Down, Northern Ireland.
It is an area of historical and geographic significance, bounded by the Quoile Marshes (now drained, but formerly extensive), the Blackstaff River, the Irish Sea and Strangford Lough. It has an oddly isolated position, virtually cut off from its hinterland, but open to invasion and influence from the east and south.
Anciently it was the name of the Irish district of Leath Cathail. As Ladcathel it was a county of the Earldom of Ulster, and later the name of the former barony of Lecale, which was then split into Lecale Lower and Lecale Upper by 1851.
