Giant aquarium (Obří akvárium in Czech) with its volume of 130 thousand liters is the largest fresh water aquarium in the Czech Republic. Since 1998 it has presented its visitors from many parts of Europe with tropical fish and plants of South and Central America, directly in the city center of Hradec Králové. The aquarium is open for visitors throughout the whole year, six to seven days a week.

Besides the aquarium with glass underwater tunnel and tropical forest, we also run our Café Piranha where you can watch real predatory piranhas while enjoying your coffee. We also offer a variety of unique experiences like individual evening relaxation for couples or our stylish conference room for business of private events.
