San Giovanni di Sinis is a tiny fishing village right in the south of the Sinis Peninsula, 19km from Oristano. Its main sight is its homonymous church, which was originally built in the 6th century using blocks of sandstone from Tharros. In the 11th century, it was transformed from a cruciform into a more conventional longitudinal layout and various extensions were added and it is this form that has remained to the present day. The church is wonderfully understated and unpretentious both outside and in, but still manages to be a fascinating place to look round. Well worth a visit whilst you’re in the area.
