Ragusa Cathedral is dedicated to Saint John the Baptist. The present church dates from the early 18th century. It has been the seat of the Bishops of Ragusa since the establishment of the diocese in 1950.
A church of San Giovanni Battista stood before the 1693 Sicily earthquake in the west of the old town of Ragusa (Ragusa Ibla) under the walls of a medieval castle, where there now stands the church of St. Agnes.
Severely damaged by the earthquake, it was rebuilt at the center of the new upper town of Ragusa in the district of 'Patro'. On 15 April 1694 the foundation stone was laid. The church was finished after just four months, so that on 16 August the same year it was opened for worship in a solemn ceremony which was attended by all the elders of the County. The short time it took for the building indicates that it was a small church, inadequate to the needs of the new district.
In 1718, therefore, the construction on the site of a larger church began. Two master builders of Acireale, Giuseppe Recupero and Giovanni Arcidiacono, oversaw the project, and some architectural details of the church of San Giovanni are typical of the Baroque monuments of Acireale and Catania, such as the monumental Baroque main entrance with rusticated columns, which has significant similarities with the marble door of Acireale Cathedral.
The interior dates from the 19th and 20th centuries. In 1950 the church became the cathedral of the newly created Diocese of Ragusa.References:
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.
