Advent Bazilika belongs on this map because it identifies a precise Budapest venue: Szent István tér, 1051 Budapest, rather than a general city-centre point. That makes it useful for a traveller comparing exact squares across a train-focused winter route. The official source had not published a complete 2026–27 date range when checked on 19 August 2026, so the season remains TBA. Standard hours are also TBA, with holiday status stored separately for the key December and New Year dates.

Its access reference is Bajcsy-Zsilinszky út on the M1, with an estimated four-minute walk under normal conditions. Admission is free and the published operating pattern is daily, but neither fact supplies an unpublished 2026–27 schedule. This is the important distinction from the confirmed Basel and Brussels entries: Advent Bazilika is a clearly located venue with useful access information, yet its future calendar still needs an official update.

Read the listing as a Budapest venue choice, not as a proxy for every seasonal activity in the city. The square identity, the short M1 approach and the explicit TBA status are the grounded details to carry into planning. If the trip depends on Christmas-week opening or a particular day, check the organiser’s current information before relying on this Place.
