The Kaliska Gate was located at the western entrance to the city, positioned on the same axis as the Kraków Gate, and underwent several construction phases from the 14th to early 17th centuries. Initially built as a wall with gates flanked by a tower, it was later expanded with a rectangular gatehouse and eventually extended by 24 meters over a moat, likely functioning as a barbican. The gate and tower were demolished based on the city's 1823 regulatory plan or possibly earlier during Prussian rule (1793-1807), but archaeological work in 2000-2001 uncovered the foundations and erected a cross on the reconstructed tower base.

The Collegiate Church of Corpus Christi in Wieluń is a 14th-century former Augustinian church built by King Casimir the Great along with an adjacent monastery. After the last monk died in 1893, the church was transferred to diocesan clergy, and in 1965 Pope Paul VI elevated it to collegiate status by reactivating the Wieluń Chapter. The church serves as both a parish church and houses the Sanctuary of Our Lady of Consolation, whose image was crowned with papal crowns in 1971.

The Franciscan Monastery in Wieluń was founded in 1629 and constructed between 1629-1634, later expanded to its current size between 1737-1754. The monastery served as a refuge for Irish monks fleeing religious persecution from 1645-1653, housed a higher seminary from 1662-1800, and was dissolved by tsarist decree in 1864 due to monks' involvement in the January Uprising before being restored to the Franciscan order in 1921. The baroque church features unique polychromy that underwent major renovation after World War II and houses paintings by 19th-century Franciscan painter Father Rafał Ernest Credo.

A central plaza of Wieluń, a city with history dating back to the 13th century, with the square itself laid out in the 14th century when King Casimir the Great granted the city municipal rights. The rectangular square measures approximately 100 by 70 meters and is surrounded by townhouses mainly from the 18th and 19th centuries, though some have older 16th-century cellars.

The bombing of Wieluń was a series of German Luftwaffe attacks on the Polish town of Wieluń on September 1, 1939, carried out by Ju 87B Stuka dive bombers as part of Operation Ostmarkflug. The sudden attack, conducted without a declaration of war, destroyed 75% of the town's buildings including the hospital and historic monuments. Casualty estimates vary significantly among historians. Some historians consider the bombing of Wieluń to be the first chronological act of German aggression against Poland, potentially marking the beginning of World War II, though there is no unanimous consensus on this matter among scholars.

Archaeological excavations conducted between 1988-91 uncovered 186 coins spanning from the 14th to 19th centuries, along with fragments of pottery, glass vessels, textiles, and religious artifacts from the destroyed church.

The former parish church of St. Michael the Archangel was Wieluń's oldest parish church, built in the late 13th or early 14th century with the first mention dating to 1308. The church was elevated to collegiate status in 1419 and received a second dedication to the Visitation of the Blessed Virgin Mary. After suffering damage during the 1939 Luftwaffe bombing, German occupation authorities decided to completely demolish the historic building by blowing it up in 1940, replacing it with wooden barracks.
