St. Stephen's Basilica is a Roman Catholic basilica named in honour of Stephen, the first King of Hungary (c. 975–1038), whose supposed right hand is housed in the reliquary. It was the sixth largest church building in Hungary before 1920. Today, it is the third largest church building in present-day Hungary.
The basilica was completed in 1905 after 54 years of construction, according to the plans of Miklós Ybl, and was completed by József Kauser. Much of this delay can be attributed to the collapse of the dome in 1868 which required complete demolition of the completed works and rebuilding from the ground up.
The architectural style is Neo-Classical; it has a Greek cross ground plan. The façade is anchored by two large bell towers. In the southern tower is Hungary's biggest bell, weighing over 9 tonnes. Its predecessor had a weight of almost 8 tonnes, but it was used for military purposes during World War II. Visitors may access the dome by elevators or by climbing 364 stairs for a 360° view overlooking Budapest.
At first, the building was supposed to be named after Saint Leopold, the patron saint of Austria, but the plan was changed in the very last minute, so it became St. Stephen's Basilica.
The Saint Stephen Basilica has played an active role in the musical community since its consecration in 1905. The head organists of the church have always been very highly regarded musicians. In the past century the Basilica has been home to choral music, classical music as well as contemporary musical performances. The Basilica choir performs often in different parts of Europe as well as at home. In the summer months they perform every Sunday. During these months you can see performances from many distinguished Hungarian and foreign organ players alike.
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
