Heritage Open Day: The church and tower will be open for stunning views over the city and surrounding countryside. Teas and cake will be on sale. All Saints Church in Bow Brickhill is predominantly 15th century, with some parts from the 12th century. The church stands above the village upon the Greensand Ridge with outstanding views from the top of the tower across the city of Milton Keynes and beyond. The tower includes a room that was used by the Royal Observer Corps in World War II, where the graffiti left by the observers is still readable. The church is surrounded by countryside, is very peaceful and well worth a visit.
