You only see what you know (Goethe)
The ancient Roman name of Ljubljana was Emona. Today one can still see some Roman elements in the city. E.g. this redesign of a part of the Roman town walls created by architect Jože Plečnik. The reconstruction of the walls is not really authentic but works as remarkable monument to the former presence of the Romans.
The city walls of Passau are still to see in some parts. This part is located near a street named Sterkgäßchen in the Innstadt. The Innstadt is a quarter of Passau, situated between the Inn river and the Austrian border. [German]
Near the museum of local history in Cologne I discovered this map located in the pavement. For me it was an interesting way to learn about the route of the former Roman town wall.
Of five town gates, only one is left. The Marientor is a gate dating back to 1445. It consists of a tower with the for the region typical conical roof and a barbican covered by a late Gothic wall-walk.
This pic show the remains of the oldest city wall (11th century) of Erfurt. The depicted wall, generally known as Innere Johannesmauer, had been demolished in 1875. Red and blue street name signs still give a hint which streets were inside or outside the city walls in earlier times.
The Aquileia Gate (Porta Aquileia) was errected in 1436 as part of the fifth ring of city walls surrounding the city of Udine. Entering the city through this gate lead to Via Aquileia where you can walk along six old palaces dating back to the 17th-19th centuries.
This is a clever way to learn about the former town wall of Wiener Neustadt. At Reyergasse 10, I saw this mural depicting the walls around the city. Some parts of the walls are still visible. E.g. the Reckturm Tower dating back to the 13th century is placed at the north-western corner of the town.
The Reckturm is a tower dating back to 13th century. After its demolition it was reconstructed in the style of 15th century. The name Reckturm (reck = rack) refers to its use as prison and place for torture. Today it houses a small museum for weapons and about torment.
Nuremberg (Nürnberg) is still surrounded by a city wall to a large extend. From my hotel located next to the wall I had this excellent view of the guard’s walkway.
Two wall ruins near the railway station of Regensburg. The wall in the foreground was built in medieval times, the wall in the background is even from ancient Roman period.
The walls of Friedberg were built with money from the ransom for Richard I of England (‘Richard the Lionheart’). The gate depicted above is a reconstruction and is known as ‘Ungartor’.
The town of Friesach is still surrounded by a water-filled moat. The structure on the left side is a reconstruction of a Bäckertauche. In earlier times a Bäckertauche was used as a punishment tool similar to a cucking stool.
