The Church of Saint Peter and Paul in Česká Lípa was a significant religious structure located at the heart of the town, on what is now Škroupovo Square. Likely constructed in the early 14th century, it served as a focal point for both Catholic and Protestant communities over several centuries. Its historical significance extends beyond its architectural style to its role within the religious and social dynamics of Česká Lípa. The church suffered multiple fires, with the final one leading to its demolition in 1820.

The origins of the Church of Saint Peter and Paul are somewhat obscure, as there are no definitive documents confirming its exact date of construction. However, historical sources suggest it was likely built in the early 14th century, coinciding with the establishment of Česká Lípa itself. Some historians propose that it may have been rebuilt on an earlier site around 1475. The church's history is intertwined with broader European religious tensions, particularly during the Thirty Years' War, reflecting the region's shifting denominational allegiances.

Architecturally, the Church of Saint Peter and Paul was a late Gothic building characterized by three naves. It featured a high tower equipped with bells crafted in Litoměřice in 1712. The interior housed several valuable altars, sculptures, and paintings, contributing to its artistic significance. Following a fire in 1617, the church underwent repairs, including relocating its bells to a newly constructed belfry in 1631.

Throughout its history, the church experienced dramatic changes in ownership and administration. Between 1608 and 1623, it was occupied by Protestants before being returned to Catholic services with support from Wenzel Treubner and Albrecht von Wallenstein in 1623. The church also served as a burial site for notable figures, including members of the Berků z Dubé family and the Vartenberků lineage.

Key events marked the church's history, notably its occupation by Protestants and subsequent return to Catholic services. Fires were significant occurrences, with the first major one occurring in 1787 and another devastating blaze in 1820 leading to its demolition. These fires not only damaged the structure but also resulted in the loss of many valuable items, though some artifacts like a baptismal font were saved and transferred to the Church of Saint Mary Magdalene.

Today, the site where the church once stood is no longer accessible as a religious monument, having been demolished after the 1820 fire. However, its historical significance remains preserved through documentation and artifacts housed in the Česká Lípa museum. Visitors interested in the town's rich history can explore these collections to gain insight into the cultural and architectural heritage of this once-prominent church.

The Church of Saint Peter and Paul stands as a testament to the religious and social transformations that shaped Česká Lípa over centuries. Its legacy, though no longer physically present, continues to intrigue historians and visitors alike, offering a glimpse into the past through preserved artifacts and historical records. For those interested in exploring the layers of history embedded within this town, a visit to the local museum provides an opportunity to connect with its storied past.
