St Stephen's Basilica

St Stephen's Basilica is Budapest's largest church and Hungary's most important Catholic building, housing the mummified right hand of King Stephen I in a golden reliquary. The real draw is the 96-meter dome climb that delivers the best central panorama in Budapest, with Parliament to the north and Buda Castle across the Danube. You'll climb 137 steps from the upper landing (after taking the lift) for views that stretch across the entire city.

Inside, the basilica feels surprisingly intimate despite its massive scale, with detailed mosaics and marble columns creating an almost theatrical atmosphere. The Holy Right chapel draws steady crowds of locals lighting candles, while tourists crane their necks at the ornate ceiling frescoes. The dome ascent involves a cramped spiral staircase that opens onto a narrow walkway circling the exterior, where wind whips through as you photograph the city sprawling below.

Most guides oversell the interior artwork, which is impressive but not extraordinary by European cathedral standards. Skip the audio guide (overpriced at HUF 1,500) and invest that money in the dome climb instead (HUF 1,200, about EUR 3). The basilica itself is free, but they appreciate donations. Sunday morning services close tourist access until 1pm, so plan accordingly. The forecourt Christmas market from late November runs decent mulled wine at HUF 1,500 per cup.
