Rundale

Rundale clachan patterns of settlement still visible in Inver, Kilcommon, Erris, County Mayo, Ireland

The rundale system (apparently from the Irish Gaelic words "roinn" which refers to the division of something and "dáil", in the sense of apportionment) was a form of occupation of land in Ireland, somewhat resembling the English common field system. The land is divided into discontinuous plots, and cultivated and occupied by a number of tenants to whom it is leased jointly. The system was common in Ireland, especially in the western counties. In Scotland, where the system also existed, it was termed run rig (with the first element either from the Scottish Gaelic roinn or the English run, and the second from the Lowland Scots rig or ridge).
