Until about 1891 a tower, possibly of the preceptory church, together with a vaulted undercroft, survived as part the Temple farmhouse.

This is recorded in Dugdale’s Monasticon Anglicanum, which states that Hubert de Rye presented the Templars with church of Aslackby with its chapel "in the year when Thomas, archbishop of Canterbury departed from the King [Henry II] at Northampton" – i.e., 1164.

[3] The word preceptory is used for the community of the Knights Templar which lived on one of the order's estates in the charge of its preceptor.

Little of its structure survives, but early descriptions and sketches indicate that its church was like that at Temple Bruer Preceptory, a chancel with an apsidal east end and a round nave to its west.

Later, towers were built at both the Lincolnshire churches, the one at Aslackby apparently around 1200, on the south side of the round nave.
