Copernicus Tower in Frombork, Medieval tower in Frombork, Poland
Copernicus Tower is a red-brick Gothic tower standing on Cathedral Hill in Frombork, Poland, once part of the town's defensive wall. It now belongs to the museum complex around Frombork Cathedral and holds an astronomy exhibition inside.
The tower was built in the Middle Ages as part of Frombork's town wall and originally served a defensive purpose. In the early 1500s, Nicolaus Copernicus used it as a place to carry out astronomical observations.
The tower displays medieval astronomical instruments that show how Renaissance scholars observed the sky. The objects on show make the working methods of that era tangible and easy to follow.
Visitors can climb the interior staircase to the upper levels, where there are open views toward the Vistula Lagoon. The steps are steep and narrow, so comfortable footwear is a good idea before you start climbing.
Although the tower is widely known as Copernicus's observatory, he did not use it as a permanent workspace but only occasionally for observations. The building where he actually lived and worked daily no longer exists.
