The name Frith comes from the
Old English fyrhoe, meaning wood or woody pasture. The first mention of Frith in historical records is in 1323 when it was called Le Frith; in 1512 it was referred to as "The Kings Frith beside Boston". Formerly extra-parochial land, Frithville was enclosed in 1802. This was one of seven new townships north of Boston that were organized in 1812. The civil townships were organized at the same time as this remote area had major projects in the three fens for installing drains to claim the land for agricultural development. This continues to be a rural area with an economy based on agriculture. Chief crops in the late 19th century were wheat and beans. The Anglican church of
Saint Peter was built in 1821, much later than many churches in Lincolnshire. It is among those built after 1810, known as Fens chapels or the Georgian group, for their style of architecture. Numerous churches in the shire predate the Protestant Reformation. St. Peter's is a Grade II
listed building. It is in the hamlet of Mount Pleasant, which was included in the township of Frithville when the latter was organized. It is one of several churches built in the area under the
Fen Churches Act 1816. In 1885 ''
Kelly's Directory'' reported that the brick-built church and the vicarage were erected simultaneously. The parish also had a
Wesleyan chapel. Frithville has a primary school and an agricultural shop. Because of repeated flooding in the Fens, several drains were constructed through this area in the 19th century to reduce water damage to agriculture and settlements. Before the drains, the land was used largely for seasonal pasture. Those projects crossing Frithville include the
West Fen Drain, the
Twenty Foot Drain, and the
Medlam Drain. In the 21st century, summer boaters travel the waterways for recreation. ==Governance==
