The Halászbástya (Hungarian pronunciation: [ˈhɒlaːzbaːʃcɒ]) or Fisherman's Bastion is one of the best known monuments in Budapest, located near the Buda Castle, in the 1st district of Budapest. It is one of the most important tourist attractions due to the unique panorama of Budapest from the Neo-Romanesque lookout terraces. The Fishermen's Bastion's main façade, parallel to the Danube, is approximately 140 meters long, of which the southern aisle is about 40 meters long, the north is 65 meters long, and the ornate central parapet is 35 meters long. Its seven high-pitched stone towers symbolize the seven chieftains of the Hungarians who founded Hungary in 895.The original walls were built in the 1700s, forming part of the walls of a castle. Several historians say that in the Middle Ages this part of the castle walls was protected by the guild of fishermen (halász), who lived under the walls in the so-called Fishtown or Watertown. The current structure was built between 1895 and 1902, in Neo-Romanesque style, on the base of a stretch of the Buda Castle walls, by architect Frigyes Schulek, who was also responsible for the restoration of the Matthias Church. Since 1987 it has been one of Budapest's World Heritage Sites as part of the Várkerület District (Buda Castle District).

The Church of the Assumption of the Buda Castle (Hungarian: Nagyboldogasszony-templom), more commonly known as the Matthias Church (Hungarian: Mátyás-templom), more rarely the Coronation Church of Buda, is a Roman Catholic church located in the Holy Trinity Square, Budapest, Hungary, in front of the Fisherman's Bastion at the heart of Buda's Castle District. According to church tradition, it was originally built in Romanesque style in 1015, although few references exist. The current building was constructed in the florid late Gothic style in the second half of the 14th century and was extensively restored in the late 19th century. It was the second largest church of medieval Buda and the seventh largest church of the medieval Hungarian Kingdom. It is a historic building with an important history. Two Kings of Hungary were crowned within its walls: Franz Joseph I of Hungary and Elisabeth, and Charles IV of Hungary and Zita of Bourbon-Parma.The church was also the location of the "Marian Miracle" of Buda. In 1686, during the siege of Buda city by the Holy League, a wall of the church - used as a mosque by the Ottoman occupiers of the city - collapsed due to cannon fire. It turned out that an old votive Madonna statue was hidden behind the wall. As the sculpture of the Virgin Mary appeared before the praying Muslims, the morale of the Muslim garrison collapsed and the city fell on the same day.

Széll Kálmán tér (Széll Kálmán Square, formerly known as Moszkva tér or Moscow Square between 1951 and 2011) is a square in Budapest. It is one of the city's busiest transport interchanges (comparable to Móricz Zsigmond körtér farther south), which is served by a station on Metro line 2, tram lines 4, 6, 17, 56, 56A, 59, 59A, 59B, 61 and bus lines 5, 16, 16A, 21, 21A, 22, 22A, 39, 91, 102, 116, 128, 129, 139, 140, 140A, 142, 149, 155, 156, 222.
