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.

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 siege of Buda took place at Buda castle (called Festung Ofen in German), part of the twin capital cities of the Kingdom of Hungary. The Hungarian revolutionary army was led by General Artúr Görgei during the Hungarian War of Independence. Part of the Spring Campaign, the siege began on 4 May 1849, ending with the Hungarian capture of the castle by assault on 21 May. Buda Castle was the only fortress throughout the entire war to be taken by storm by the besiegers on either side. All other fortresses capitulated following agreements between besiegers and besieged. The siege of Buda was also the shortest siege of the war (18 days). The senseless bombardment of Pest by Austrian commander Major General Heinrich Hentzi caused destruction of classic buildings on the shores of the Danube. Other regions of the capitals also suffered heavy damage due to the artillery duels between the two sides. The capture of Buda Castle completed the liberation of the Hungarian capital cities (Buda and Pest). Thanks to this, the second Hungarian revolutionary Government, led by Bertalan Szemere together with Governor-President Lajos Kossuth, returned from Debrecen, the interim capital of the Hungarian revolution, to the capital of Hungary. On 21 May 1849, the same day as the capture of Buda, the two emperors Franz Joseph I of Austria and Tsar Nicholas I of Russia signed the final treaty in Warsaw, which agreed on the intervention in Hungary of 200,000 Russian soldiers (and an 80,000-strong reserve force, if necessary), in order to help the Austrian Empire crush the Hungarian revolution.

The Constitutional Court of Hungary (Hungarian: Magyarország Alkotmánybírósága) is a special court of Hungary, making judicial review of the acts of the Parliament of Hungary. The official seat of the Constitutional Court is Budapest. Until 2012 the seat was Esztergom.The Constitutional Court is composed of 15 justices since September 1, 2011 (previously, the Court was composed of 11 justices). The members then elect the President of the Court (Chief Justice) from among its members in a secret ballot. One or two vice-presidents, appointed by the President of the Court, stand in for the President in the event of his absence for any reason. The constitutional court passes on the constitutionality of laws, and there is no right of appeal on these decisions. The Constitutional Court serves as the main body for the protection of the Constitution, its tasks being the review of the constitutionality of statutes, and the protection of constitutional order and fundamental rights guaranteed by the Constitution. The Constitutional Court performs its tasks independently. With its own budget and its justices being elected by Parliament it does not constitute a part of the ordinary judicial system.
