Laufer Tor Tower

The Laufertorturm, built around 1377, is one of the four distinctive round main towers of the former city fortifications. In 1552, the gate tower was badly damaged during the Margrave War. In order to protect the tower from further targeted attacks, it was encased in a round casing around 1556. (Source: tag-des-offenen-denkmals.de)

The gate is documented as part of the last city wall as early as 1377 and took over the function of the Laufer striking tower of the penultimate city wall. It accommodated traffic on the Goldene Strasse from Sulzbach and Prague and the northbound road from Bayreuth.[1] Access to the city was via a wooden bridge into an inner courtyard and the actual city gate. A side gate and a ramp made it possible for carts and wagons to enter the ditch in the northern half of the city. The gate with the armory was reinforced by two ramparts in front of the city wall made of heaps of earth and massive retaining walls.[2] At the end of the 19th century, the complex was adapted to the requirements of the growing traffic and all buildings apart from the round tower were demolished.The section of the city wall south of the Laufer Tor between Rathenauplatz and Pegnitz is called the Laufertormauer. After that, the alley Laufertormauer inside the city wall and the main street Laufertorgraben outside were named. The Laufertorzwinger is located north of the Laufer Tor.At the southern end of the Laufertor wall, on the north bank of the Pegnitz, the Hübnerstor was built in 1892 through the city wall and under the Zwinger. The pedestrian gate was named after the nearby Hübnersplatz.Source: de.wikipedia.org/wiki/Laufer_Tor

bunker
In 1941 the Laufertor tower was converted into a bunker. It was one of the 15 high and 8 underground bunkers in Nuremberg. With a wall thickness of around four meters and a reinforced ceiling of 1.4 meters, it was predestined for civil protection. On seven floors and a total area of around 200 m², it officially offered space for 146 people. Heating, washing facilities and toilets were part of the bunker. The costs for converting the Laufertor tower into a bunker amounted to around 132,000 RM.[5] The bunker is not connected to the Laufertorkeller bunker system.Source: Wikipedia
