O2 universum is a cutting-edge multifunctional congress and cultural center located in the heart of Prague.

Opened in October 2019, this state-of-the-art venue offers unparalleled versatility and innovation, making it a modern and unique event space. Designed to host a wide range of events, from international congresses and exhibitions to cultural performances, O2 universum sets a new standard for large-scale gatherings.

Directly connected to the O2 arena, the largest indoor venue in the Czech Republic with a seating capacity of over 18,000, O2 universum enhances the potential for hosting combined mega-events. Adjacent to both venues is the STAGES HOTEL PRAGUE, operated under Marriott International’s Tribute Portfolio brand. The hotel features 300 stylish rooms and suites, a lifestyle restaurant and bar, dedicated meeting facilities, a fitness center, and ample parking, ensuring a seamless experience for guests.

The first dinner of the Euroheat & Power Congress, on 3 June, will take place in Červený Jelen (Red Stag), a restaurant situated in the historic Sporck Palace in Prague, which is a fusion of Baroque and modernist architecture. Built by Count Sporck in 1694, the palace features a Classical-style addition from 1790 and later enhancements by Josef Gočár, influenced by the Rondocubist movement, in the 1920s.

The site’s rich history includes serving as a bank, Gestapo headquarters, and government offices, reflecting its deep historical significance.

Architect Stanislav Fiala led a 2014 restoration, preserving historic details and blending them with modern elements. Today, it combines a historical ambiance with contemporary dining experiences.

The second dinner of the Euroheat & Power Congress, on 3 June, will take place in the special Neo-Renaissance National House of Vinohrady. This building, located right in the city centre, was built in 1984 and it is a celebration of Vinohrady district. The name Vinohrady in English literally means vineyards. The district of Vinohrady is situated on the territory of the former royal vineyards. This three-winged structure represents the spirit of the national liberation mood, and an uncompromising emphasis on the cultural heritage of the Czech nation – its artists and history.

The National House of Vinohrady is no longer just the centre of Vinohrady, as it was in the past, but is now an equal of all the major cultural and social venues in Prague.

Currently, the National House of Vinohrady is listed as a National Cultural Monument and is owned by the Ministry of Culture of the Czech Republic.
