St. James's Parish Church was built in the Baroque style between 1613 and 1615 on the site of an older Gothic style church, erected in the early 15th century by the Augustinian Order. In 1598, the old church was acquired by the Jesuits and thus became the first Jesuit church in the Slovene Lands and one of the first in the Inner Austria. The interior was designed by the Italian architect Francesco Robba, who designed the main altar, and the Slovene stonemason Luka Mislej, who designed the entrance portal and the stone side altars. After the Ljubljana earthquake of 1895, the church was renovated by the Linz-based architect Raimund Jeblinger and the interiors were redesigned by Janez Šubic. Nevertheless, much of the original Baroque style has remained intact.
On the side of the church there is a column erected in 1682 to commemorate the Habsburg victory against the Ottoman Turks in the Battle of Saint Gotthard. The column, dedicated to the Virgin Mary, was designed by the Salzburg-based artist Wolf Weisskirchner upon the plan by Johann Weikhard von Valvasor.
In the late 1920s, the square in front of the church was renovated by the Slovene architect Jože Plečnik, and in the early 1950s by the architect Boris Kobe. Opposite St. James's Church is the Gruber Palace, which houses the Slovenian National Archives.
References:The stone church of Gamla Uppsala, built over the pagan temple, dates from the early 12th century. Due to fire and renovations, the present church is only a remnant of the original cathedral.
Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
