Europe’s largest ice-skating rink is located at the edge of the City Park, enclosed between Heroes’ Square and Vajdahunyad Castle. This is the second such establishment in Europe, built in 1926, shortly after the construction of the one in Vienna, Austria. In the wintertime, a continuous, 12,000 m2 large ice surface is generated by special machinery underneath the lake. From spring until autumn, various cultural and recreational events await visitors. In the summertime, the area is usually filled up with water, and boats can be rented. During the last few years, however, the lake remained dry; this is because the water corroded a part of the cooling system, and it needs to be repaired before the lake can be filled up with water again.
