Many of his paintings can be seen in museums in Germany, Austria, Croatia, and Slovenia while others are held by private owners in those same countries, as well as the United States of America, Great Britain, Scandinavia, and Greece.

In 1893 he worked on the picturesque decoration of buildings at the World Exhibition in Chicago as well as panoramas and dioramas of the marine painter de:Hans von Petersen.

In addition, Kircher worked as an illustrator for popular German and foreign magazines and publishers of which only a few can be mentioned: The Leipziger Illustrierte Zeitung or the modern illustrated weekly Reclams universe (Leipzig), the writings of the Austrian (Vienna) and the German fleet association (Berlin) and the Viennese publisher Philipp & Kramer, for which he designed the postcard series "Dalmatia and Istria".

Between 1895 and 1900 he was a professor at the Art Academy in Trieste and married Romana Salmassi[8] in the Chiesa di Sant'Antonio Taumaturgo[9] on 15 October 1898.

In 1904, after a short stay in Vienna, Kircher moved from Trieste to Dresden, where he lived until 1906 and where he joined the General German Art Cooperative as a freelance artist.

Kircher concluded his life's work with a series of one hundred paintings which documented the development of German shipping over a millennium and which hung in the Institute and Museum of Oceanography MfM.

In the remarkable Austro-Hungarian Navy Museum "Gallerion",[30] in Novigrad, Istria (Croatia), multiple replicas and photographs of well known Kircher paintings will be shown.
