The Church

All Saints Theddlethorpe is a fourteenth and fifteenth-century church with Norman origins, known as the Cathedral of the Marsh - a testament to its impressive length and spacious light-filled interior, as well as the quality of the interior carvings.

The church is managed by the Churches Conservation Trust and faces many challenges, including from the impacts of bats.

In 2019, the project commissioned a report on the stonework from Skillingtons, which concluded that there were multiple conservation needs.

Despite its lonely grandeur, the outside of the church has a colourful appearance as the local north Lincolnshire greensand is patched with brick and limestone.
