The construction of the Jesuit building complex began between 1654 and 1662 with the construction of the college building, and in 1670, the building of the church, designed by the Prague architect Dominik Orsi, commenced. The construction, completed in 1685, was overseen by J. Canevalle. Between 1700 and 1729, the wing adjoining the northern side of the church—today’s Reduta, which housed the Jesuit school—was built. This completed the complex, composed of four single-story wings surrounding a rectangular courtyard divided into two parts by the church building. The façades facing Masaryk Square are articulated with a large pilaster order, while the façades of the southern and eastern wings are smooth. The church's design was based on Vignola’s Roman Church of Il Gesù, but reduced by omitting the transept and dome. It was built as a single-nave oriented structure with a rectangular-ended presbytery, side chapels, a sacristy aligned with the presbytery, and two towers on the western façade. The presbytery and sanctuary are vaulted with barrel vaults with lunettes, richly decorated with stucco ornamentation. The interior walls are divided by pilasters with Roman capitals. On each side of the main nave are three chapels opening into the nave through semicircular arcades, and above them are open loggias with baluster railings. The painting of St. Francis Xavier above the main altar is the work of the Prague painter Jan Jiří Heintsch. The carpentry, including the Baroque pews, confessionals, and original tabernacle, was crafted by Adam Freytag. The sculptures were created by Ondřej Schweigl from Brno. The presbytery features illusionistic painted architecture by the Třeboň painter Tadeáš Supper. In front of the main altar is a family crypt where the remains of the college’s founder, Kateřina Zoubková of Zdětín, were transferred. The symmetrical main façade was modified during the reconstruction in 1754–1755. It is divided by a large pilaster order supporting a profiled cornice with a triangular pediment. The façade ends with a tall volute gable containing a niche with a statue of St. Francis Xavier. The towers are topped with flattened four-sided onion domes with open lanterns and finials. The nave is covered with a gable roof, while the side chapels are covered with lean-to roofs. The church’s roof was laid over the main nave in 1679, but it burned down two years later in a city fire. Immediately after the fire in 1681, a new roof was built. Since then, no major alterations had been made to the roof structure. In the autumn of 2006, restoration of the roof structure began, and the work was completed in May 2007. The truss had been seriously damaged by wood-decaying fungi and insects. Severely affected parts that were no longer structurally sound were replaced with new ones. Where only part of a wooden element was damaged, only the affected portion was replaced, and it was joined with the original part to preserve as much of the original 300-year-old wood as possible. At the same time, the roof covering was also replaced. Although the Jesuits had sought to build their own church since their arrival in the town, circumstances did not allow it for many years. It was not until 1670 that the decision was made to build, though the foundation was anything but simple. Because of the swampy ground, the foundations had to be laid at a depth of up to three meters. Oak beams joined with oak clamps formed the first layer. Alder piles were driven side by side on top of this, and only then was the masonry of stone and lime built. Complicated political and financial circumstances prolonged the construction period. Nevertheless, the unfinished church was consecrated for worship in 1677. After the fire that destroyed its roof, it temporarily became the parish church, as the Church of St. George, which had served that role until then, was far more severely damaged. In 1682, the church was solemnly consecrated, and the construction of the Baroque church continued until 1685. The interior was then furnished, even into the early 18th century. The church attained its current appearance in 1754–1755, when both towers were completed and the façade was finalized. In 1760, the Jesuits finally abandoned plans to extend the church along its main axis, and the Třeboň painter J. T. Supper created a painting of a perspective colonnade on the back wall, continuing the real colonnade and creating the illusion of an extended nave. It took 100 years to complete and decorate the church. The church continued to serve its purpose even after the Jesuit order was dissolved, and when the parish Church of St. George was demolished in 1785, the Church of St. Francis Xavier took over as the parish church. In the following years, further modifications, repairs, and additions to the interior decoration were carried out. Under the supervision of the Monument Office in Brno, restoration work was carried out on the church in 1940. In 1997, severe flooding caused numerous structural problems but also revealed part of its hidden history. During the removal of flood damage, frescoes from 1681 by Domenico Gagini were discovered in the Chapel of St. Victoria after damp plaster was removed. In the first half of the 18th century, this work had been covered with new plaster when the chapel was rebuilt as the Loreto Chapel. The uncovered frescoes were restored. The Baroque reliquary of St. Victoria from this chapel also underwent demanding, costly, and lengthy restoration. It was given a surface finish of 24-carat gold and reinstalled in the chapel in August 2006.
