The church is named after St Pega. She was the sister of Guthlac, who set up a hermitage in the Peterborough fens. Pega built her hermitage in imitation of her brother. Guthlac and Pega came from one of the great noble families, and it seems as if Pega received a grant from the King to set up her hermitage. It is said that the current church at Peakirk is built on the site of Pega's retreat. Interestingly, the history books state that Pega sailed up the river Welland to attend her brothers funeral, and healed a blind man from Wisbech on the way.
This church was built in the 11th Century, and the dedication to St Pega is a unique one. A north aisle was added in 1170, with a south aisle added some 50 years later. This church is nationally famous for a series of wall paintings, mainly to be found on the north aisle.
