History of St George's Chapel in Slupsk began 500 years ago. The first information on it can be found in documents from1492. Since we do not know the exact date when it was put up, researchers suggest the 15th century in general. Reasons why the chapel was built are closely related to St George's Hospital. The hospital was intended for people with symptoms of infectious diseases and it had rooms used for quarantine. Its building was situated 200 metres away from The New Gate, next to the road running down to Slawno. Reasons for its location far away from a built-up area resulted from safety of healthy people. When there was no epidemic, hospital rooms were used as a shelter for the elderly, the homeless and the disabled. The hospital's staff included lonely ladies and widows – that was a strict rule.

In order to guarantee pastoral care for seriously ill patients, a hospital chapel was put up. The chapel was situated where the today's east part of the house in 8 Tuwima Street in Slupsk is. After the Reformation, which took place in Slupsk in 1525, the chapel building was neglected and slowly began to fall into ruin. With efforts of J. Hoppe's (a mayor) foundation, in 1610, services and masses were held there again. In 1681, both the buildings: the hospital and the chapel, burnt down in a fire. They were restored later with efforts of Gustav Lehmann's (a mayor) family, his wife and sons, who made works run faster. Eight years after the fire, both the buildings were rebuilt, the chapel got a new domed roof and a wooden vault.

After another 130 years, the hospital buildings stopped to play their primary role. The hospital was pulled down in 1820 and a new hospital with internal construction fully suitable for actual needs took its place. In 1894 (according to the drawing in L. Buttger's book), the chapel had a flat ceiling, in 5 niches (8 in total) there were recesses above the floor. The altar was situated in the second niche (the right one when you look from the door side). Right next to it, the pulpit with the dome sticking up over it and the stairs and the seats in front of the altar were situated. It is an interesting fact that the supports of the chapel wall are inside and not outside the building as commonly observed in the Gothic architecture. In a photograph from 1912, we can see that the chapel was plastered from the outside and the roof was covered with pieces of wood put parallel to the eaves. The chapel has a Baroque spire covered with shingles today.

In 1903, because of its bad technical state and location close to the new city hall, the building was pulled down. In 1912, the chapel was taken apart (with an approval of the Prussian minister of culture) and moved to a new place on a square between today's Jagiełło Street (Ringstrasse), Jana Pawla II Street (Wallstrasse) and Lutoslawskiego Street (Butowerstrasse). The square was then named after Schmatzken-Berg but today every resident of Slupsk knows it as Jerzego Waldorffa Square. In 1935, a plaque being a tribute to all Slupsk inhabitants who were killed during the First World War was hung in the chapel. Right after the Second World War, the unsecured plaque began to decay. In March 1968, it was taken over by the Middle Pomerania Museum.

Lack of necessary installations (as a historic object it needs to conform to certain standards) brought about that it could not be used as a storeroom or an exhibition place for museum pieces. In the half of 80s, a protective reinforced-concrete ring beam was attached around the chapel foundation and the roof base was firmed with a steel ring. On 30th December 1994, the chapel became a property of Roman Catholic St Jack's Parish in Slupsk. For six years, the chapel has revived as it has been used by Stefan Morawski's Klub Plastyka to hold numerous exhibitions. Klub Plastyka is an association of amateur artists that was established 51 years ago. Up to now, several dozens of exhibitions has been organised. They were enjoyed by many visitors who deny a thesis that only entertainment for the masses can draw much interest.

In Andrzej Grzybkowski's publication "Centralne kaplice gotyckie Pomorza Srodkowego", chapels from Slupsk, Koszalin and Darlowo were recognised as architectonic imitations of the Holy Sepulchre in Jerusalem. In the medieval Europe, rotundas of the Holy Sepulchre were put up since the 5th century. Pomeranian dukes, including Warcislaw VII, Eryk Pomorski and Boguslaw X, went on pilgrimages to the Holy Land. Eryk Pomorski and Boguslaw X are founders of cemetery chapels in Darlowo and Wologoszcza. As commonly known, the Slupsk chapel is built on an octagonal plan. In medieval copies of the Holy Sepulchre from Jerusalem, buildings having 8 and 12 walls buildings were the most common ones. Medieval Christian theologians believed that 8 is a number representing the Resurrection, a beginning of a new life, Jesus Christ and christening.
