The <strong><a href=\"https:\/\/www.designboom.com\/tag\/architecture-in-the-czech-republic\/\">Prague<\/a><\/strong> Planetarium has undergone a major modernization that goes far beyond just replacing its projection equipment. The <strong><a href=\"https:\/\/www.designboom.com\/tag\/renovation-architecture-and-design\/\">renovation<\/a><\/strong> of the protected building, designed by architect Jaroslav Fr\u00e1gner in the 1950s, was complex. It required removing layers of interventions from recent decades to make way for the installation of revolutionary LED projection technology. The largest LED screen of its kind in the world. At the heart of the project is a new hemispherical screen from the American company COSM, 22 meters in diameter, with an incredible 45 million pixels. Visitors can experience an immersive spatial illusion with extraordinary color depth and realism.<\/p>\n<p>all images by <a href=\"https:\/\/www.boysplaynice.com\/\">BoysPlayNice<\/a><\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<h2 class=\"wow wow-yellow\">collcoll redesigns the auditorium for immersive viewing<\/h2>\n<p>\u00a0<\/p>\n<p>The central Zeiss Jena projector was moved outside the main hall by agreement with heritage conservators, freeing space for a new auditorium design. <strong><a href=\"https:\/\/collcoll.cc\/\">Architects<\/a><\/strong> from collcoll studio designed a stepped geometric layout that visually lifts the audience above the horizon. Capacity increased by 20% to 277 seats, with a spatial arrangement supporting comfortable and safe movement. The seats were custom-designed with a Czech manufacturer, and they are now adjustable, ergonomic, and comfortable enough to keep visitors attentive. Acoustic treatment hidden behind the projection dome further enhances the illusion of infinite space.<\/p>\n<p>\u00a0<\/p>\n<p>The installation of new technology required new energy and technical facilities, integrated into the building with maximum respect for its protected structures. Cooling and heat recovery were designed considering the planetarium\u2019s location in the heart of Stromovka Park. Heat from the screen is stored in six deep wells (each 200 m deep) in summer and used to heat the building in winter. The dome itself has a thermal output comparable to three family houses, so the heat is reused within the building.<\/p>\n<p>new LED dome lights up the Prague Planetarium interior<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<h2 class=\"wow wow-yellow\">Historical preservation merges with future-forward design<\/h2>\n<p>\u00a0<\/p>\n<p>The renovation also affected the foyer and facilities. The original exhibition at the entrance was replaced by a circular LED screen serving as an additional presentation surface. A newly designed cloakroom separates incoming and outgoing visitor flows, increasing comfort. Over the summer of 2025, a new simulator exhibition in the basement is set to open, along with a shop at the new exit, after completing outdoor landscaping. An inappropriately placed ramp will be removed from the adjacent rosarium, simplifying barrier-free access through the shop. This modernization positions the Prague Planetarium as a world leader in immersive education and culture with its unique LED dome technology, offering visitors an unprecedented visual experience of the cosmos.\u00a0<\/p>\n<p>collcoll studio redesigns the auditorium for immersive viewing<\/p>\n<p>\t<!-- CLOSE ARTICLE CONTENT --><\/p>\n<div class=\"fullwidth-image\">\n<div class=\"layout-box\">\n<div class=\"page-content\">\n<p>45 million pixels create a seamless hemispherical display<\/p>\n<\/p>\n<\/div>\n<\/div><\/div>\n<p>\t<!-- OPEN ARTICLE CONTENT -->\t<\/p>\n<p>viewers experience deep color and spatial illusion<\/p>\n<p>a 22-meter LED dome redefines spatial projection<\/p>\n<p>seating redesigned for ergonomics and adjustability<\/p>\n<p>\t<!-- CLOSE ARTICLE CONTENT --><\/p>\n<div class=\"fullwidth-image\">\n<div class=\"layout-box\">\n<div class=\"page-content\">\n<p>historic structure updated with contemporary technology<\/p>\n<\/p>\n<\/div>\n<\/div><\/div>\n<p>\t<!-- OPEN ARTICLE CONTENT -->\t<\/p>\n<p>geometric stepped seating raises audience above the horizon<\/p>\n<p>energy systems adapted to preserve the protected building<\/p>\n<p>integrated acoustic treatments enhance spatial perception<\/p>\n<p>\t<!-- CLOSE ARTICLE CONTENT --><\/p>\n<div class=\"fullwidth-image\">\n<div class=\"layout-box\">\n<div class=\"page-content\">\n<p>renovation merges historical preservation with future-forward design<\/p>\n<\/p>\n<\/div>\n<\/div><\/div>\n<p>\t<!-- OPEN ARTICLE CONTENT -->\t<\/p>\n<p>\u00a0<\/p>\n<p><strong>project info:<\/strong><\/p>\n<p>\u00a0<\/p>\n<p><strong>name:<\/strong>\u00a0Prague Planetarium<br \/>\n<strong>architect:<\/strong>\u00a0<a href=\"https:\/\/collcoll.cc\/\">collcoll<\/a> | <a href=\"https:\/\/www.instagram.com\/collcoll.cc\/\">@collcoll.cc<\/a><\/p>\n<p><strong>design team:<\/strong> Adam K\u00f6ssler, Kri\u0161tof Hanzl\u00edk, Libor Ml\u00e1dek, Michal Fousek<\/p>\n<p><strong>client:<\/strong> <a href=\"https:\/\/www.planetum.cz\/\">Observatory and Planetarium of Capital City Prague<\/a> | <a href=\"https:\/\/www.instagram.com\/planetum.cz\/\">@planetum.cz<\/a><\/p>\n<p><strong>location:<\/strong> Kr\u00e1lovsk\u00e1 obora 233, 170 00 Prague, Czech Republic<\/p>\n<p><strong>dimensions:<\/strong> 22 m screen diameter 45 000 000 LEDs screen resolution<\/p>\n<p><strong>photographer:<\/strong>\u00a0<a href=\"https:\/\/www.boysplaynice.com\/\">BoysPlayNice<\/a>\u00a0|\u00a0<a href=\"https:\/\/www.instagram.com\/boysplaynice\">@boysplaynice<\/a><\/p>\n<p>\u00a0<\/p>\n<p><strong>project management: <\/strong><a href=\"https:\/\/www.contractmanagement.cz\/\">CManagement<\/a> [Arno\u0161t T\u00e1borsk\u00fd, Dan Kouba]<\/p>\n<p><strong>technical supervisor:<\/strong> Ji\u0159\u00ed C\u00eds<\/p>\n<p><strong>energy management:<\/strong> <a href=\"https:\/\/tosystem.cz\/\">TO SYSTEM<\/a> [Jaroslav Smejkal, Jakub Jan\u010fourek]<\/p>\n<p><strong>ventilation:<\/strong> <a href=\"https:\/\/atrea.eu\/en\/\">Atrea<\/a> [Barbora Pa\u0159\u00edkov\u00e1, Zden\u011bk Zik\u00e1n]<\/p>\n<p><strong>cooling:<\/strong> Michal Je\u017eek<\/p>\n<p><strong>structural engineer:<\/strong> \u0160t\u011bp\u00e1n Thondel<\/p>\n<p><strong>lighting concept, electricity:<\/strong> <a href=\"https:\/\/www.sysloop-engineering.com\/\">sysloop engineering<\/a> [Miroslav Frolec, Anatolyi Obryn]<\/p>\n<p><strong>acoustic design:<\/strong> <a href=\"https:\/\/www.aveton.cz\/\">Aveton<\/a> [Dominik Cvetler]<\/p>\n<p><strong>acoustic consultation:<\/strong> Petr Roll<\/p>\n<p><strong>acoustic insulation:<\/strong> <a href=\"https:\/\/www.awal.cz\/\">A.W.A.L.<\/a> [Kate\u0159ina Vol\u0161\u00edkov\u00e1]<\/p>\n<p><strong>fire safety:<\/strong> Ilona Muzikov\u00e1<\/p>\n<p><strong>sanitary:<\/strong> <a href=\"http:\/\/www.tzb-block.cz\/\">TZB-BLOCK<\/a> [Jan Smr\u010dek]<\/p>\n<p><strong>server room:<\/strong> <a href=\"https:\/\/www.altron.net\/\">Altron<\/a> [Jakub Odlas]<\/p>\n<p><strong>power line connection:<\/strong> <a href=\"http:\/\/www.pring.cz\/\">Pring<\/a> [Jan Vo\u010dko]<\/p>\n<p><strong>geothermal wells:<\/strong> <a href=\"https:\/\/www.gerotop.cz\/\">Gerotop<\/a> [Tom\u00e1\u0161 Kuchta]<\/p>\n<p><strong>landscaping:<\/strong> <a href=\"https:\/\/www.her.archi\/\">her architecture<\/a> [Alice Bou\u0161kov\u00e1]<\/p>\n<p><strong>geodetic survey:<\/strong> Pavel Keprta, Jan Kopeck\u00fd<\/p>\n<p><strong>LED projection technology:<\/strong> <a href=\"https:\/\/www.cosm.com\/\">Cosm<\/a><\/p>\n<p><strong>dome structure:<\/strong> <a href=\"https:\/\/www.spitzinc.com\/\">Spitz<\/a><\/p>\n<p><strong>LED technology, projection software:<\/strong> <a href=\"https:\/\/www.es.com\/\">Evans &amp;
