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.

Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
