Mörby slottsruin

Mörby slottsruin is a castle ruin near Norrtälje made of stone, with remains standing several stories high across a substantial area. The ruins show the characteristic structure of a medieval fortification with towers, walls, and foundations that still reveal the original architectural design.

The castle was founded in the late 14th century and came under the control of a powerful family in the 15th century, who held it for generations. A fire in the 18th century destroyed much of the structure but left enough stonework standing for it to remain visible today.

The ruins reflect how Swedish nobility displayed power and status through solid stone construction, with family emblems and architectural details visible on remaining walls. The scale of the structure tells visitors something about the social hierarchy and resources available to those who ruled from this place.

The site is reachable by a short walk from a nearby parking area, so no long hike is needed to reach it. The ruins are open to walk around freely, meaning you can explore them at any time of day without worrying about schedules.

The ruins are now home to a population of bats that live in the dark crevices and gaps of the stone walls. These protected animals have made the abandoned structures their home, showing how nature reclaims such old places.
