It was erected between 1605 and 1614 by the architect Georg Ridinger [de] for Johann Schweikhard von Kronberg, Prince Bishop of Mainz.

Schloss Johannisburg is located in the city of Aschaffenburg, in the district of Lower Franconia of the state of Bavaria, Germany.

The palace was erected between 1605 and 1614 by the architect Georg Ridinger [de] for Johann Schweikhard von Kronberg, Archbishop of Mainz.

The considerable expense came from the taxes of his fief: Eichsfeld, Erfurt and the Mainzer Oberstift (the part of the Electorate administered from Aschaffenburg) made the largest financial contributions.

During the reign of Ludwig I, Schloss Johannisburg served as the summer residence of the King, who referred to Aschaffenburg as his "Bavarian Nice".

This roof design was in contrast to Ridinger's plans, who had intended the central keep to mirror the appearance of the castle's corner towers.

[1] Schloss Johannisburg is open to the public and hosts several museums: Staatsgalerie Aschaffenburg, a gallery of paintings (with works by Lucas Cranach the Elder), the Paramentenkammer of the palace chapel (with vestments from the former treasury of Mainz Cathedral), the residential rooms (furnished in Neoclassical style) and the Municipal Palace Museum (arts and handicraft).

There is also the world's largest collection of architectural models made from cork, built by court confectioner Carl May and his son after 1792.
