The church, rebuilt in 1877, but with the remains of its 12th-century tower, is built within the bailey of a former castle, Toot Hill. Pirton Grange, which was remodelled in the 18th century, is in the north of the parish, and is a particularly interesting, moated Elizabethan house with a timber-framed gatehouse. Hammonds Farm and Rectory Farm, with its tithe barn, are also Elizabethan.
The Icknield Way Path passes through the village on its 110-mile (180 km) journey from Ivinghoe Beacon in Buckinghamshire to Knettishall Heath in Suffolk. The Icknield Way Trail, a multi-user route for walkers, horse riders and off-road cyclists also passes through the village.
There are two churches in Pirton – one Methodist, one Anglican. There is a village school which teaches children from reception to Year 6. Many students continue on at Hitchin Priory. There are two local pubs – the Motte and Bailey on Great Green, and the Fox on High Street. Pirton has both football and cricket clubs.
