Basilica di Santo Stefano Maggiore was established in the 5th century. Originally dedicated to both Saint Zechariah and Saint Stephen, it was later dedicated to Saint Stephen only. Throughout its history, has undergone several reconstructions, expansion and restoration.
The original church building was built around the year 417 on the initiative of the future bishop Martinianus. It was destroyed by fire in 1070 and it was rebuilt in romanesque style in 1075.
On 26 December 1476 it was the site of the assassination of Duke Galeazzo Maria Sforza, who had come to the basilica for the celebration of the patron saint. On 30 September 1571 in Santo Stefano was baptized the painter Michelangelo Merisi, better known as Caravaggio.
Since 1594 the church underwent a series of interventions, including enlargement of the apse and of the main altar in the early 17th century.
The church preserved the bodies of saints Martinianus, Ausanus and Mansuetus, archbishops of Milan, in 1988 translated to the Milan Cathedral. St. Charles Borromeo also translated here the bodies of saints Leo, Arsazius, Marinus, Mammes and Agapetus.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
