The landscape park was created between 1778 and 1828 with the help of Goethe. It has sentimental as well as classical and post-classical features. Characteristic of the park are the numerous visual axes that connect prominent points inside and outside the park. Numerous garden architectural works of art as well as the Roman House, Goethe's Garden House, the Park Cave, the Liszt House and the Palace Museum on the northern edge of the park offer the opportunity to spend the whole day here. The Park an der Ilm is part of the UNESCO World Heritage Site "Classical Weimar", which is a unique testimony to the cultural epoch of Weimar Classicism and reflects Weimar's outstanding role as an intellectual center in the late 18th and early 19th centuries.
