The 18th century telescope was located in an indoor observatory on the top floor of the building, with the sides of the circular dome roof opening to the left and right, allowing a long telescope to be pointed diagonally upwards to observe the starry sky. Scholars gathered in a fenced-in corridor surrounding the large telescope, which cut a circle through the floor and rose up from the floor below, discussing something in the royal castle in the sky.
