Early Roman ruins from Vienna's earliest days as a Roman fort in the basement of the Fire Brigade Building.

A collection of 3000 clocks of all types, including a prized 18th-century astronomical clock.

This museum houses a collection of artifacts from the Roman settlement of Vindobona, as Vienna was then known.

Believed to be the oldest church in Vienna, although excavations around the foundations of two other churches (Stephansdom and Peterskirche) have challenged this view. Earliest mention of the church in historical records is in 1200; the current structure dates from the Romanesque period, while the interior was renovated during the Baroque era.
