Ununge Church was probably built at the end of the 13th century, but has been rebuilt and expanded on several occasions. The easternmost part of the church has been dated to the end of the 14th or to the 15th century.
In its layout, the church is a typical example of medieval churches from Uppland. It consists of a rectangular, single-nave church hall consisting of three bays of which the easternmost is the choir. There is a sacristy to the north and a church porch to the south. The oldest of the church fittings are the triumphal cross from the 13th century, which has been described as one of the finest of its kind and Sweden and which resembles contemporary triumphal crosses from Denmark, and the baptismal font, also from the 13th century. The interior of the church was renovated in 1897.

The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
