Stephansplatz is the epicenter of historic Vienna, making it an excellent place to start your walking tour of the city (or a day of shopping). The square hosts an eclectic blend of architecture spanning over 800 years. The most prominent is the Gothic design of the 12th century St. Stephen’s Cathedral (off camera). On the left is Palais Equitable, built in 1891 for an insurance company. At street level of the building is Stock im Eisen. This oddity is a seven foot tree trunk with hundreds of nails pounded into it for good luck. The tree dates back to 1400. Contrast these to the Haas House, a glass Postmodern design constructed in 1990.
