Watchtower Vodojem Bohumín, Water and observation tower in Nový Bohumín, Czech Republic

The Watchtower Vodojem Bohumín is a circular brick and concrete tower, 39 meters tall, with eight levels in Nový Bohumín. It was converted from a 1934 water reservoir (8.5 m diameter) into an observation tower, small pension and information centre, with a side glass staircase of 187 steps and a lift.

This structure was built in 1934 as a water storage facility serving the town's water needs for decades. Following renovation, it opened to visitors in 2006 with new roles as an observation point and lodging facility.

The tower is known locally as Penzion ve věži (Pension in the Tower) or Maják v Bohumíně (Lighthouse of Bohumín). It now houses a small pension and the town information centre, and is run by the municipal company Bospor. The conversion won the Top Invest award for best investment of 2006 at the Brno Building Fair in 2007.

The tower is open year-round and charges an entrance fee. Access is barrier-free, with a lift as well as 187 steps in a glazed side staircase. Tourist trails and cycle paths lead to the site near the Bohumín Aquacentre.

The tower's 2005–2006 conversion won the Top Invest award for Best Investment of 2006 at the Brno Building Fair in 2007. The city runs it through its company Bospor, and the site sits at 200 m above sea level beside the Aquacentrum.
