Pesti Vigadó, the Romantic-style concert hall built in 1864 but badly damaged during WWII, faces the river to the west of Vörösmarty tér. Reopened in 2014 after a 10-year closure and reconstruction, the building has been fully restored to its former grandeur. Additional space has been set aside for temporary exhibitions and there's now a fantastic terrace affording expansive views over the Danube. It's a fantastic place to catch a classical concert in glamorous surrounds.
Start your visit in the ground-floor gallery space, before ascending the magnificent stone staircase for a peek into the 2nd-floor concert hall. A lift will whisk you to the 5th- and 6th-floor exhibition rooms and from the 6th you can step out onto the panorámaterasz (terrace) to take in the views.
