This preceptory was founded at the beginning of Henry II’s reign, around 1164. The first benefactors were Hubert IV of Rye⁽¹⁾, his wife Margaret of Percy⁽²⁾ and his son-in-law, John Marshall⁽³⁾.

Hubert de Rye donated the church and a chapel in Aslackby to the Templar Order. These properties are situated along an ancient Roman road leading from London to the borders of Scotland. The chapel is incorporated into the preceptory’s buildings, whilst the church continues to be used by the villagers.

In 1275, the Templars of Aslackby were accused of holding land in Rippingale to the detriment of the king Edward I, and of having refused to assist the sheriff in several matters in the villages of Rippingale, Gautby and Dowsby. The records that have survived do not mention the legal consequences of these two cases.

Following the dissolution of the Order in 1312 and a period under royal control, the Aslackby preceptory came into the hands of the Hospitallers of St John in 1338, but they did not establish a new preceptory there. They retained a house at Aslackby, complete with a chapel, and around 200 acres of land, which were leased to Henry de la Dale, the secretary to the Earl of Lancaster⁽⁴⁾.
At that time, the buildings were in rather poor condition and virtually uninhabitable. This property was subsequently incorporated into the Temple Bruer estate.

Today, nothing remains of the preceptory. The last remaining structures, including a large square tower, were demolished at the end of the 19^th century. The preceptory’s chapel was dismantled and incorporated into a building now known as "Temple Farm", a farm built on the site of the preceptory’s buildings.
