Äußerer Ringmauerturm

Of the town fortifications in the valley that were completed in the 15th century, two circular wall towers still stand today. With its embrasures, the outer ring wall tower located above the gatekeeper's house of the Altheim Gate, together with four other round towers and four half-round towers, protected the part of the outer ring of town walls that lay around the suburb in the valley. This defence system was built in the 15th century using the latest weapons technology, and the defensive citizens of Horber defended the town wall with heavy hooked rifles, which frightened the approaching enemy even when they smelled the glowing fuses.
