File:Carlton Scroop, St Nicholas church, interior (26286452415).jpg

The church dates from the 12th Century, and is mainly built of Lincolnshire oolitic limestone, however brown rubble and ironstone masonry was used for the lower part of the square tower and is Anglo-Norman. There is a large Norman arch between the tower and nave. Most other parts of the church are in the “Decorated” style although the North doorway (now blocked) is also Norman. This was used by the Scrope family to access the church and was sealed up when the last member of the family died. The South porch dates from the 13th century as does the chancel and the two arches either side of the Nave. A date of 1616 on the porch indicates that some later alterations were carried out. The two aisles and the top part of the tower are 14th century structures and the upper part of the tower dates from 1632. A tablet inside the tower reads “On Sunday in the night the 14th November 1630 the steeple of this church fell and broke down the roofs of the nave and two aisles”. The traceried stone font is more than 500 years old and in the Chancel there is a double piscina and sedilia set into the stonework of the South side wall.
