The village is included in the ecclesiastical parish of Hough-on-the Hill, part of the Loveden Deanery of the Diocese of Lincoln.

[3] Gelston is referred to in the 1086 Domesday account as "Chevelestune"[4] in the manor of Hough-on-the-Hill, and in the Loveden Hundred of Kesteven.

In 1066 Earl Ralph was Lord of the Manor; after 1086 this transferred to Count Alan of Brittany, who also became Tenant-in-chief.

[5] In 1885 Kelly's Directory noted: "at Gelston there is a place of worship for Wesleyan Methodists; and an ancient cross".

[7] The medieval limestone cross on the village green dates from the 15th century, is Grade II listed and is a scheduled ancient monument.
