Monks Risborough is a lovely village in Buckinghamshire at the foot of the Chilterns that has been in existence since pre-Norman times. Not quite as old but still very interesting is a building near the church of St Dunstan (originally between the church and a farmhouse) that dates from the 16th century.
This is the Pigeon House which now stands in a recreation ground. Pigeons were bred for food in the house though later it was used by the nearby farm as a cattle shelter. One curiosity is a door on the Northern side of the house which does not match the rest of the architecture and may have been originally part of another building.
