Around three-fourths of palaces and castles remained open last year, Glazer said. He added that five opened their gates to the public for the first time during the year.

One of those venues, the Esterházy Palace in Tata - pictured above - , in northwestern Hungary, was the most popular palace or castle last year, drawing about 55,000 visitors.

This year, another ten renovated palaces and castles will open to the public, Glazer said.

Hungarian palaces and castles drew over 213,000 visitors in 2019.

The number fell to around 141,000 in 2020, when pandemic restrictions were in place.
