The Huwilerturm in Zug is the smallest of the four outer city towers and has a charming history. It was built around 1524/25 and was known for a long time as the "Hof-Turm" until it was bought by a citizen named Huwiler in 1697.

One of four preserved city towers. A small part of the former city wall borders its walls. Right next to the Huwiler Tower, there is a pretty park shaded by tall trees, which invites you to play and relax.

Huwilerturm, Zug The year the Huwilerturm was built cannot be determined precisely from documents, but according to Linus Birchler it was in 1524/25. Other sources give the year of construction as 1519 and name a master builder named Huwiler as the builder. The tower's current name does not come from this Huwiler, but from a later owner of the same name, who came into possession of the tower in 1697. The name "Huwilerturm" only gradually caught on, however, because the name "Hoof Thurm" (after the property "Hof im Dorf" or "Hof am Burgbach") can still be found on the Landtwing city map from 1770. For this section, see also the Zug New Year's Gazette 1983. Access to the Huwilerturm was originally via the battlement of the city wall on the city side on the first floor. It was not until 1826 that the tower was given a ground floor entrance - from the outside - and two windows. The outer ring of walls Six round towers, four gates and a passageway formed the new ring of walls. The total length was 850 meters and increased the size of the city from 0.4 to 2.8 hectares. In addition to the existing buildings such as St. Oswald's Church, the castle, the village residential and commercial district, etc., there were large undeveloped areas in the new city area for a long time.

Wildenburg ruins In the early 13th century, the Lords of Hünenberg built a residential castle on the spur high above the Lorzentobel, but it was abandoned after 200 years and later used as a quarry. In 1985 the ruins were saved from final decay and carefully restored. Since then, the Wildenburg has once again been an impressive and publicly accessible testimony to Baar's past. An exciting experience for castle and medieval fans! The worth seeing castle ruins with remains of the round tower, bering and palace are located on a promontory above the Lorzentobel, 3.5 kilometers east of Zug. At the parking lot at the western end of the Lorzentobel Bridge, the hiking trail branches off from the main road in a southerly direction. After around 20 minutes of hiking in steep terrain, shortly after the beautiful Schwarzenbach waterfall, you reach the ruins. The castle area is freely accessible. Please pay attention to the barriers (danger of falling). Free parking spaces on the Zug-Menzingen main road, 300 meters northwest of the castle. https://youtu.be/djjFowSPsXE
