Villa Agnes, Cultural heritage monument in Radebeul, Germany

Villa Agnes is a two-storey country-house villa on a syenite base with a sandstone facade and a very shallow gable roof crowned by wooden acroteria. Its main south front faces the garden, with a polygonal annex and veranda on the right and a flat-roofed outbuilding on the left. The garden holds an octagonal pavilion with a copper cupola and a bowl fountain.

The Serkowitz builder Moritz Ziller applied in February 1879 to develop the corner plot at Nizzastraße 13, today Lößnitzgrundstraße 2, with the neighbouring plot; construction finished in 1880. From 8 April 1891 to December 1895 Karl May rented the house from the Dresden owner Friedrich Wilhelm Sauerzapf and wrote numerous books there before buying Villa Shatterhand. In May 1891 burglars stole May's notebook, recovered when the culprit was arrested. Around 1900 an octagonal garden pavilion was erected at the plot corner.

The house is also called Villa Petersdorf. Karl May rented it from 1891 to 1895 under the address Nizzastraße 13 and wrote numerous books there; in May 1891 a burglar stole his notebook, which was recovered after the culprit's arrest. May then barricaded the property behind a wooden fence with iron spikes.

The villa stands at the corner of Lößnitzgrundstraße and Nizzastraße in Oberlößnitz, its main garden front facing south toward Nizzastraße. The grounds are divided into three flats, so the house is a private residence and not open for tours. The octagonal garden pavilion and the shell fountain can be seen from the street; the property is a stop on walks through the Radebeul villa quarter.

In May 1891 burglars broke into the villa and stole Karl May's notebook; it was recovered when the previously convicted culprit was arrested shortly afterwards. May then barricaded himself on the property, which was enclosed by a wooden fence topped with iron spikes.
