The consulates-general in Berlin, Bremen, Cologne, Hamburg, and Munich closed upon the collapse of Austria-Hungary.
A legation was established in 1866 (although diplomatic missions had been accredited to various city states since much before, e.g. Venice in 1553); raised to an embassy in 1877.
The consulates-general in Beirut, Smyrna (now İzmir), and Trebizond (now Trabzon), closed when Austria-Hungary collapsed.

The legation was established in 1691; the envoy to Copenhagen was also accredited to Oslo, Norway, from 1906 to 1917.
