text: REPORTING ERRORS- The County Seat for Lane County is the city of Eugene, not a property lot. The original Courthouse was built on the Public Square as part of the land donations of the Mulligan and Skinner families. The Skinner Donation Warranty Deed shows Two Agreements with the Lane County Commissioners regarding designation of the County Seat (the city) and County Courthouse (building location). http://www.mudcitypress.com/parkblockshistory.html
