Built in 1211, the village church of Algenstedt is one of the oldest religious buildings in the region. The late Romanesque fieldstone building is largely preserved in its original state. Whenever restoration work and renovations were carried out - such as in the 18th century - they were done with care and consideration for preserving the historical structure. From the time of the church's construction, the two southern portals and a walled-up round-arched window date back. The distinctive feature of the church is the squat square tower with its unique tent roof, the only one like it in the whole of Altmark region. It and the church bell from 1500, one of the oldest in Altmark, have become part of local legend. It is said that the tower once was one of the highest and the bell one of the most melodious far and wide. Supposedly, the wealthy people of Kalbe did not approve of this. Through intrigues, they supposedly managed to have the old church tower of Algenstedt demolished and the bell buried.
