The parish church in Wińsko was first mentioned in sources in 1272 (parish priest Nicholas) and again in 1354 under the call of the Blessed Virgin Mary. In 1432, it was destroyed by the Hussites, but it was rebuilt ten years later. During the town’s fire in 1514, the church again was almost completely burned down, only the peripheral walls remained. The rebuilding was carried out in the years 1549-1562. From that moment the church was already carrying the call of Holy Trinity, as it was taken over by Protestants. Due to lack of funds, the planned tower was not constructed, only a wooden belfry was erected. In the years 1669-1671, the building was thoroughly renovated. In 1696, in realtion with the Counter-Reformation in Silesia, after the death of the last pastor, the church was closed. In the hands of the Protestant commune, it returned only in 1707. In 1826 the sacristy was rebuilt, and in 1876 a neo-Gothic tower was added to the west façade. At that time, the walls and equipment of the building were also renovated.
The church was built in the north-eastern part of the town, near the city’s defensive walls. It received an east-west orientated form, consisting of a three-bay and three-aisle nave of a hall form and trapezoidal shape. From the eastern side, an elongated, three sides ended chancel was added with the width of the central nave, and on the southern side of the nave a Gothic porch was added a little later. The nave of the church was surrounded with stepped buttresses, and the eastern gable of the nave was decorated with blendes. Large pointed windows with tracery were placed between the buttresses (except the north wall of the presbytery, where it was planned to place the sacristy). The church interiors were covered only with wooden ceilings and separated into aisles by pointed arcades resting on elongated, rectangular pillars with bevelled corners.
The church has retained its original Gothic shape, but was quite significantly transformed in the early modern period, especially during the neo-Gothic renovation. At that time, a western tower and a porch at the presbytery were erected, a toothed frieze was placed along the upper, external façades of the nave and the presbytery, significant parts of the walls were faced with machine bricks, window tracery and the nave gables were replaced and the interior plastered. Probably in the Baroque period, a row of lower windows under Gothic ogival windows was pierced, and the galleries were founded inside the church. No original portals have survived in the church.
