The stein seen here represents one of the Nuremberg towers, namely the
Frauentorturm, rebuilt to its present form in 1558, to guard the
Frauentor (a gate in the city wall). Among the multiple Nuremberg
towers, this one is unique due to its arched windows and round top
window. This stein is usually attributed to Merkelbach & Wick for
Theodor Wieseler. However, earlier versions have also been seen with
Freising / Hauber & Reuther capacity marks.
Quite often you will see a stein for sale simply called a Nuremberg
Tower. That may be accurate so far as it goes, but there are four great
round garrisoned towers in the old city walls of Nuremberg, and they
are nearly all different! They each guard a gate in the walls.
Their individual names are 1. Spittler, 2. Frauen, 3. Laufer and 4.
Neu. The full names are made up by the name, followed by gate (tor),
followed by tower (turm): so e.g., Spittlertorturm.
In 1849 the city wall was opened up close by the Frauentorturm, and a
new gate, the Königstor was built for traffic access to the railway
station. Due to essential road widening, the Königstor was demolished
in 1892. Because of its proximity to the Königstor, the Frauentorturm
was, and still is, often wrongly referred to, as the Königstorturm.
Today, the Frauentor has pedestrian access only.
To confuse the issue, quite often you hear the Dürerturm mentioned.
This never actually existed. It is in fact the Neutorturm which just
happens to be next to the Albrecht Dürer house and I suspect was named
to please the tourists.
