St. Ursus Cathedral, Solothurn

St. Ursus Cathedral, Solothurn (also Cathedral of St. Ursus and Victor)
St. Ursus Cathedral (also Cathedral of St. Ursus and Victor) is the cathedral of the Roman Catholic Diocese of Basel in the city of Solothurn, Switzerland.
The early neoclassical church building, dedicated to the martyrs Ursus and Victor, was begun in 1762 by Gaetano Matteo Pisoni of Ascona on a site where two previous buildings had probably stood since the early Middle Ages. It was completed in 1773 by his nephew Paolo Antonio Pisoni. The interior is decorated with stucco by Francesco Pozzi.
The extensive cathedral treasury includes, among other things, the Hornbach Sacramentary, a statue of the Virgin Mary, and a manuscript created around 983 in the Reichenau Monastery.
The 66-meter-high onion dome was occupied for a long time by a tower guard. A drawing by Peter Thumb from 1708 indicates that a second, also unrealized, tower was already under discussion for the previous collegiate church.
The Church of St. Urs and Victor served as the minster of the St. Ursenstift since the Middle Ages and, in its current form, became the episcopal church of the Diocese of Basel, which had relocated to Solothurn, in 1828.

Stylistically inspired by Italian Baroque architecture with elements reminiscent of French classicism, it took more than four decades to complete this impressive building due to financial constraints during construction.
