Grymyr Church

The sister churches on Gran were built in the 12th century and expanded in the 13th century. The two stone churches, St. Mary's Church (Mariakirken) and St. Nicholas' Church (Nikolaikirken), are built only 30 meters apart. The churches have been named "Sister Churches" after the legend of two sisters who, due to unfriendliness, had to have their own church. But it was actually not uncommon in the Middle Ages for churches with different functions to be built close together. After a lightning strike in 1813, St. Mary's Church remained a ruin until the 1860s when the church was restored with roofs and windows. In 1912-15 it was again restored to be used as a burial chapel. In 1990-92 it was restored for use as a parish church. The church is built of rough-hewn stone with a chancel that is almost as wide as the nave.

Nikolaikirken is the larger of the two medieval stone churches on Granavollen. The two churches go by the name "Sister Churches". The oldest of the sister churches, Mariakirken, was already completed when Nicolaikirken was built around 1150. The Romanesque church resembles the Old Cathedral in Hamar, the Old Aker Church in Oslo and the Ringsaker Church. The common model was St. Hallvard Cathedral.

The Tingelstad church was built of unpainted red bricks according to the drawings of Schirmer and von Hanno. The church is characterised by neo-gothic forms and is relatively large and richly designed. In 1925, the slate at the top of the tower was replaced by copper. In 1958, the church was extended with a baptismal waiting room on the first floor and a chapel in the basement.
