Despite being in the busy Nene Valley between Wellingborough and Thrapston, Irthlingborough church seen from the far side of the river retains a timeless and surprisingly isolated quality, its extraordinary tower remains the highest building in the area.
The result is a very pleasing and harmonious whole.
Externally, one of the most impressive features is the large east window, its elegant five lights crowned by an ogee head.
Internally, there is a most unusual architectural feature, a strainer arch inserted in the late 14th or early 15th century to prevent the church collapsing. Its function may be purely structural, but is was made in such a delicate, lattice like way that it looks decorative.
There are other surprises: there are at least five Green Man carvings in the church. As always, their meaning is enigmatic, and their feeling unsettling. They are often thought of as pagan figures, but many experts think they depict the fate of those who only had material lives, and are entirely Christian symbols.
