Tieto Towers, Office skyscraper pair in Ostrava, Czech Republic

Tieto Towers is a pair of connected office high-rises near Ostrava's Náměstí Republiky: the taller tower rises 53 metres over thirteen above-ground floors, the shorter 42 metres over ten. Two underground levels hold garages with 300 parking spaces, and the complex offers 22,000 m² of lettable office space.

The project, first called IQ Ostrava Office Park, was to be finished in 2009 with a 24-storey, 90-metre tower. The 2008 economic crisis led developer CTP to postpone construction, which began only in 2011 after Tieto signed as tenant. Tieto opened the buildings on 20 October 2012.

Locals called the planned complex Ostrava's twins or Ostrava's skyscrapers before construction. The name Tieto Towers came from the tenant Tieto, which opened the buildings on 20 October 2012; since the firm's 2023 move to Organica in Karolina, CTP manages them as IQ Ostrava.

The two towers stand by náměstí Republiky, with 300 parking spaces in two underground garage levels. Tieto moved its Ostrava staff out in 2023 to the Organica building in the Karolina area, so the offices are now let under the name IQ Ostrava.

The two towers were nicknamed Ostrava's twins before construction began. The original 2008 plan for a 24-storey, 90-metre tower was shelved during the economic crisis; the built taller tower reaches 53 metres with thirteen above-ground floors, the lower 42 metres with ten.
