The Old Logie Kirk is one of the oldest Christian sites in Scotland, being established during the reign of King David I of Scotland (between 1124 and 1153). A church dedicated to St Serf was built here by at least 1183. The church was rebuilt in 1380 and survived in use until after the Reformation (1560). The current ruins are from a church commissioned by Rev Alexander Fargy who served the parish from 1560 to 1592. The church was ruinous in 1684 and Rev George Shaw organised its reconstruction.
The manse stood to the west in the grounds of Airthrey Castle and dated from around 1590, Rev Fargy having resided in Tullibody. A new manse was built in 1698 by Rev Douglas.
The church was originally linked to a priory at North Berwick under the diocese of Dunblane Cathedral but post-Reformation came under the patronage of Robert, Lord Elphinstone.
The remnants of the original church lie to the north of the current church. The tiny churchyard has many ancient stones (including some 12th century hogback graves) and several notable burials.

The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
