Viewtower Fajtův kopec, Observation tower in Velké Meziříčí, Czech Republic.

Rozhledna Fajtův kopec is a 42-tonne observation tower in Velké Meziříčí shaped like a DNA double helix. It stands on reinforced-concrete piles sunk 16 metres into the ground. Two trios of counter-twisted columns are linked by stair flights and a circular ring that carries the viewing platform. The ground-level part is a round and rectangular structure housing the ski-lift ticket office, toilets and operator facilities.

The first proposals for a lookout tower appeared in 2009, when the operators of the Fajtův kopec ski slope sought an additional attraction. The design by Václav Hlaváček and Jáchym Pecht of Studio Acht was chosen, but high costs delayed construction. A 2013 grant of 5.3 million CZK and a public collection of 300,000 CZK helped fund the project, whose total cost reached 9.4 million CZK. The tower was built and opened on 20 June 2015, and in 2015 it was named Lookout Tower of the Year and received an honourable mention in the Vysočina Region's Stavba Vysočiny competition.

The tower's name comes from Fajtův kopec, the hill above Velké Meziříčí where it stands. Each year the slope below hosts Fajtfest, a three-day music festival drawing thousands of listeners of mostly harder genres; the 2018 tenth edition featured Emmure and Hed PE from the USA, Crystal Lake from Japan, Crazy Town from the USA and Betraying the Martyrs from France.

The tower stands on Fajtův kopec above the D1 motorway; the upper end of the Fajťák ski lift is right by the tower, and the slope is skied on the side facing away from Velké Meziříčí. The lower lift station is by a reservoir on the stream, where a boulder wall stands. A bikepark called Fajťák lies above the motorway.

The tower's shape follows a DNA double helix: two sets of three columns twist in opposite directions, joined by stair flights and a circular ring that carries the viewing platform. The whole structure weighs 42 tonnes and rests on reinforced-concrete piles driven 16 metres into the ground. In exceptional visibility the Alps can be seen from the top.
