Gut Seestermühe, Manor house in Seestermühe, Germany.

Gut Seestermühe is a manor house in Seestermühe, Schleswig-Holstein. The single-storey, nine-axis building has a central projection facing the lime avenue, a balcony with black metal railing above the main entrance, and a red-orange tiled roof with a small square panel in the pediment. Outbuildings include an octagonal brick tea pavilion with a domed roof and a brick family mausoleum.

The estate was first recorded in 1141, when it was held by the Archbishop of Bremen. It passed through several owners before the von Ahlefeldt family took possession in 1494 and made it their seat.

The long lime tree avenue leading to the manor follows French garden design, with four parallel rows of trees shaping the approach to the main building. Walking along it gives a clear sense of how such layouts were meant to guide visitors toward the house.

The estate is set in the rural village of Seestermühe and can be reached on foot from the center of the settlement. Taking your time to walk through the park and around the outbuildings makes for a more complete visit.

The Glockenhaus, a brick building with a saddle roof and a small roof turret carrying a clock and bell, is the estate's working building. It burned down in 1900 and was rebuilt in its present form, then converted in 1958, partly to store pome fruit. The sources do not say it was a faithful copy of the earlier building.
