Bessastaðakirkja is a church in Álftanes situated a few meters away from the President´s official residence in Bessastaðir. Construction of the current church began in 1773 and ended in 1823 when the tower was built. Even though unfinished, the church was consecrated in 1796. Bessastaðakirkja was built of stones taken from the nearby lava called Gálgahraun and is one of the oldest stone buildings in Iceland. It´s been documented that the church has stood in Bessastaðir since the year 1200, but some say that it could have been there even since year 1000, when Iceland became a Christian country. The present stone church replaced the old wooden church which was demolished.
