The oldest manor house in Amberg, located in the heart of Altstadt.

Anyone wishing to admire a medieval toilet should turn to the right side of the old fortress. There, a bay window can be seen that was once used as a privy. Due to the height of the bay window, there was enough space underneath for a kind of cesspool. Every few months, the contents were emptied from the street at night.

In the center of Marstallgasse/Eichenforstgasse lies what is probably Amberg's oldest surviving stone building, the massive, light-colored plastered "Alte Veste" (Old Fortress). It boasts a rich history. It is unclear, however, whether its origins date back to Bamberg times. However, it already existed when Amberg passed to the Wittelsbach Duke Ludwig II of Bavaria in 1269. During the Electoral era, the building served as a residence and the seat of the vicarage until the completion of the new palace in 1420. The property, referred to as Eichenforst in sources from the 15th to 18th centuries as "Eichenforst," was granted as a knight's fief after it became dispensable for governing and administrative purposes. After 1794, the property was converted into a noble city palace, as documented by the marital coat of arms above the entrance portal. The builder was Baron Ludwig von Egcker, who married a daughter of the governor, Franz Ludwig, Count von Holnstein. The "Alte Veste" (Old Fortress) was in the hands of aristocratic residents until the beginning of the 20th century. Only after extensive renovations did it become occupied by the management of Stadtbau Amberg GmbH in 1985.
