The necropolis belongs to the Co-Cathedral Parish of St. Alexander [pl] and is located on Zarzecze Street in the western part of the city.

Among the notable graves are those of prominent residents of Suwałki, including Teofil Noniewicz, Edward Szczepanik, and Father Jerzy Zawadzki.

[1] The origins of the Roman Catholic parish cemetery in Suwałki date back to 1820, when the burial site was moved from its location near what is now Konstytucja 3 Maja Park.

[3] In 1820, due to the start of construction of the new church and ongoing regulatory works in the city, the cemetery was relocated beyond the Czarna Hańcza river, where a wooden chapel was built at the new burial site.

In July 1852, the Civil Governor of Augustów issued an edict ordering the expansion of the cemetery due to the lack of burial space.

[3] In the early 21st century, the old section of the cemetery suffered acts of vandalism, including theft of historic stone gravestones and metal crosses and parts of monument fences.

[3] Many of the older graves are neglected and in disrepair; some have lost their burial mounds and tombstones, leaving only monuments or pedestals, which are sometimes overturned or buried.

[3] Some tombstones are no longer in their original positions, and in certain cases, they have been reused, with inscriptions on both sides of the stone, likely due to the thriftiness of either stonemasons or the deceased's family.

The most distinguished monuments are situated near the chapel and include the graves of notable Suwałki residents, such as Father Jerzy Zawadzki and Edward Szczepanik.

[3] The cemetery reflects the wealth of Suwałki's community across the ages, offering insights into the economic status of those buried and the regard in which their families held them.

Based on the locations and grandeur of individual monuments, it is possible to gauge the prominence of specific families in Suwałki at different times, particularly within the cemetery's oldest section.

[3] The mass grave of seven victims of German terror is located in the northeastern part of the cemetery, near the fence along Grunwaldzka Street.

The monument includes the date marking the beginning of the Sejny Uprising—23 August 1919—along with a plaque listing the names of the fallen, the POW emblem, and the following inscription:[7]From your blood and souls' suffering, freedom for the Republic was born.The section dedicated to soldiers of the Polish Military Organization is located along the main avenue of the cemetery.
