Studnitz Pyramid, Pyramid-shaped tomb near Ernestinum grammar school in Gotha, Germany.

The Studnitz Pyramid is a small burial pyramid of Seeberg sandstone in central Gotha, near the Ernestinum Gymnasium. It was erected after 1779 during the lifetime of Hans Adam von Studnitz in his baroque garden, of which about two thirds were later built over by the school in 1837. The court sculptor Friedrich Wilhelm Döll is considered its builder.

The monument was built after 1779 by Friedrich Wilhelm Döll, a student of French sculptor Jean Antoine Houdon, as a burial site for local court official Hans Adam von Studnitz. Its construction coincided with a broader European interest in pyramid-shaped tombs inspired by ancient Roman and Egyptian sources.

The pyramid is named after Hans Adam von Studnitz, the Gotha chief court marshal who had it built in his own garden during his lifetime. Its form was later taken up in Classicism for tombs modelled on the Pyramid of Cestius in Rome, as in Canova's monument for Archduchess Marie Christine and the Karlsruhe Pyramid.

The pyramid stands near Gymnasium Ernestinum in central Gotha, on the remainder of the Studnitz garden that the state of Thuringia transferred to the city as a public park. About two thirds of the original baroque garden was built over in 1837, so the monument is now seen in a schoolyard setting rather than a private garden.

Original architectural drawings from the construction period survive and show precise plans for the interior sarcophagus and burial chamber layout. These documents reveal how carefully the geometric proportions were calculated before the monument was built.
