The Great Synagogue in Sosnowiec was constructed between 1894 and 1896 at, what is today, 16 Dekerta Street. Its construction was made possible by funds provided by wealthy Jewish traders from Sosnowiec. It was required to rapid demographic growth in Sosnowiec[1.1]. A thorough renovation was carried out in 1910.

Above all else, its facade is well-known. Base on a rectangle, it had three floors. On the ground floor, viewed from the entrance, there were three doors - one opening onto the main section, one for women and one leading to the women's section which was probably located above the landing.

The Germans blew up the synagogue on 9 September 1939 and then ordered the ruins to be demolished.

Today, the site of the former synagogue is occupied by a commercial centre. There is no indicative signage indicating what once stood here.
