The oldest part of Lovö Church has been dated back to the later part of the 12th century. According Berit Wallenberg it was built as early as the 11th century. It is also believed that an even older wooden church existed on this site. Church sermons are held in the church, normally once a month, and for certain Christian holidays.
The church is unusually small and narrow. It was extended to the east, first in the 13th and further in the 17th century. Churches built during this time were built with a weapons room, a foyer where people going to church had to lay down their arms before entering the church itself. This weapons house was demolished in 1798, and an entry was made in the west side of the attached church tower. There are also five Viking Age memorial runestones that are located outside the Lovö church.
The sanctuary of the church was created around 1670. The architect is believed to be Nicodemus Tessin the Elder, who was working on Drottningholm Palace around this same time. Inside the church are 30 gravestones, several of which belonged to people employed at Drottningholm palace. The interior was renovated in 2004.
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.
