There are two adjacent medieval churches in Gran called as Søsterkirkene, the sister churches. According to local folklore, the two churches were commissioned by two sisters who had fallen out and therefore would not be seen in the same church. It is, however, not uncommon for medieval churches with different functions to be built close to one another.
The smaller one, dedicated to St. Mary, was built probably before 1150. It is a single nave church, which either acted as a monastic church or a church for Gran parish and contains Romanesque and Gothic elements. A fire in 1813 gutted the church and it was not rebuilt until 1859. Until recently it was used as a chapel, but is now open for normal services. It can seat around 150 people.
The larger of the two churches is called Nikolaikirken (St. Nicholas Church). This church probably acted as a church for Hadeland parish and can seat around 250 people. Because of later rebuilding it is difficult to establish an exact date of construction. Based on stylistic evidence, however, it is thought that the church was built sometime between 1150 and 1200. The church is built as a basilica church with solid Roman columns and plastered walls. Much of the original interior has been lost in fires and in subsequent rebuilding.
In the south-eastern part of the churchyard there is a medieval stone tower, Klokketårnet, the original function of which is unknown. It is possible that the tower, which from the mid-19th century was used as a bell-tower, was originally used as a defence tower or refuge. The 11th century Granavollen Runestone can be found behind Nikolaikirken.
The towers of the Søsterkirkene form the base coat of arms to Gran municipality. Noted poet and journalist, Aasmund Olafsson Vinje, is buried in the cemetery of Søsterkirkene. A monument with a bust of Vinjes by sculptor Brynjulf Bergslien was erected at the site.
References:The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
