Untertorbrucke (Lower Gate Bridge), Bern

The Lower Gate Bridge is the oldest surviving bridge across the Aare River in Bern and an important reminder of the city’s medieval development. The first crossing was built in 1256, only a few decades after Bern’s foundation in 1191, and for centuries it remained the city’s only bridge to the eastern riverbank.

The original structure was made largely of oak and may have been partly covered. It included defensive features such as a fortified tower and a central guardhouse. The bridge even survived an attack during King Rudolph of Habsburg’s siege of the city in 1288.

After severe flood damage in 1460, the wooden bridge was gradually replaced with a stone structure. The reconstruction included new fortifications and a small chapel. Over time, crenelated walls, covered battlements, gates, and a drawbridge strengthened the crossing.

By the 18th century, these military features had become obstacles to growing traffic. Renovations in 1757 removed much of the medieval fortification and introduced decorative additions, including a Baroque triumphal arch. Further 19th-century changes replaced the sandstone parapets with iron railings and removed the eastern gate and drawbridge.

Today, the narrow stone bridge still carries pedestrians and local traffic. From it, visitors can admire the turquoise river, the steeply rising Old Town, and Nydegg Church above. It is particularly attractive in the morning or late afternoon and provides a scenic route between the Old Town, the Bear Park, and the riverside paths.
