Y brif Ty yn yr ardal yw plas Boduan. Cartref i teulu pwysig yn hanes Sir Gaernarfon.

The hillfort on Garn Boduan is an excelent example of the first inhabitants of Llyn. A listed monument it dates back to pre-roman times. with a subsequent re-building and then a medeival fort built on the sumit. On it's south and eastern slopes are two early farmsteads.

The principal house in the area is Plas Boduan, formerly the seat of the Wynne family who also totaly re-built the parish church.
