While by Polish standards Marki is a relatively young town, with approximately 31,000 residents, it is one of the fastest-growing cities in the Masovian province.

Marki has been long associated with industry, and while manufacturing still takes place, the service sector is booming.

North-east of Marki, there is a 100-metre high mast used for radio relay links by Telekomunikacja Polska and Centertel.

A plaque on the side of this building commemorates the passing of one of the most influential figures of modern Lithuanian culture.

Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, Marki was occupied by Germany until 1944.
