St. Anna Tunnel, Antwerp

One unique sight worth the visit on foot or the bicycle is the St. Anna Tunnel. What may seem like your average underpass is actually built under the river Scheldt, which runs through the middle of the city.

Truly a feat of engineering, what makes the Tunnel even more fascinating is that it was built in 1931. It is believed that the city had thought long and hard about connecting the two banks of the river via a bridge, however that would seriously interrupt navigation and traffic to the port, which is why the decision of building a tunnel was made.

The St. Anna Tunnel is 572 m long and at a depth of 31.57 m. one can enjoy the rustic look of the Tunnel as the antiquities like the wooden staircase and escalator are still very much in use. The tunnel was built in attempt to connect the old town to the new, developing side across the river.

So, if you are looking for a surreal adventure, there is one right in the heart of the city.
