Historically, the area of Põhja-Tallinn has been used for industrial and military purposes (mainly during the soviet time), nowadays the industry is leaving the city. For example, the structural plan for the seafront port area in Paljassaare peninsula located in Põhja-Tallinn, outlines the development of a former industrial port into a modern living, business and leisure environment with a port for yachts and liners in the next 10 to 15 years.
