A significant sight of Altenstadt, Schongau, is the Romanesque basilica minor of St. Michael with remains of medieval wall painting and several examples of Romanesque sculpture.
The basilica was built between 1180 and 1220 as the parish church of the settlement later known as Altenstadt in Upper Bavaria, Schongau. The late Romanesque building, made of tuff stone, has been almost entirely preserved or restored in its medieval form. The basilica is the only vaulted sacral building of the late Romanesque style in Bavaria. The most famous and significant artwork in the basilica is the 'Great God of Altenstadt.' The monumental 3.20-meter-high crucifix is flanked by depictions of Mary and John (copies, with the originals found in the Bavarian National Museum in Munich), situated on the modern rood screen above the choir entrance. The artwork dates back to the early 13th century. Instead of a crown of thorns, the Savior wears a gold band, depicting him as Christ the King.
In the choir and nave, several Romanesque and early Gothic frescoes have been preserved or uncovered. In the right (southern) side aisle, above the baptismal font, one can see the crucifixion, while in the choir, there is an image of the Archangel Michael as the weigher of souls and the Annunciation. On the inside of the west wall, during the renovation of the old organ in 1994, an eight-meter-high representation of Saint Christopher (circa 1200) was uncovered. The original baptismal font from the time of the church's construction has also been preserved. The chalice-shaped basin features reliefs of the Archangel Michael, the Madonna with Child, Saint John the Baptist, and the baptism of Jesus.
The Royal Palace was built in the first half of the 19th century as the Norwegian residence of King Charles III, who also reigned as king of Sweden and otherwise resided there, and is the official residence of the present Norwegian monarch. The crown prince resides at Skaugum in Asker west of Oslo. The palace has 173 rooms.
Until the completion of the Royal Palace, Norwegian royalty resided in Paleet, the magnificent town house in Christiania that the wealthy merchant Bernt Anker bequeathed to the State in 1805 to be used as a royal residence. During the last years of the union with Denmark it was used by the viceroys of Norway, and in 1814 by the first king of independent Norway, Christian Frederick.
