Lärbro Church was probably built between 1260-1280. The unusual octagonal steeple was erected in the 1300s. The interior date made mainly from the times after Reformation. The murals in the church vaults are originals. In the chancel floor, by the chancel portal, there is a tombstone in memory of Nicolaus (Nils) Taksten from 1274.
To the west of church is a defence tower, which dates from the 12th century. It was built several storeys high with a lavatory on the third floor. Today, the defence tower is used as a belfry.
References: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.
