The windmill of Seidla Manor was built in the 18th century and it is one of the few Dutch type windmills in the cultural history of Estonia that has been preserved with all fittings and in its original function. The windmill is rare because it is the only windmill that has all its original fittings and its original appearance in continental Estonia. Seidla Windmill also represents the typology of manor windmills as it is located a little distance from the centre of the manor on a visible hill. The number of such preserved windmills in manor ensembles all over Estonia is less than 5.
