St Thomas à Becket Church
Northaw's church crowns the ridge beside the Two Brewers. The present building, listed Grade II*, was built in 1881 by C. Kirk and Son of Sleaford after fire destroyed its predecessor of 1809.
Look in the churchyard for a survivor of far older days: a 15th-century octagonal font. The tower holds six bells.
Check opening times locally; services are held most Sundays.
