Tallinn is composed of two different cities,Toompea (Upper Town) and Lower Town. Upper Town was the residence of knights, gentry, and clergy (built during theXlll-XlV centuries) while Lower Town was the home to craftsmen and free citizens. Lower Town was built during the XlV-XVl centuries. The relationship between the two cities had been anything but cordial. A large stone wall was erected ( which remains to this day) to keep the citizens from each respective city from straying into forbidden territory.
The most impressive architectural achievement of the medieval masons was the Town Wall taking over 300 years to complete. Many towers were erected along the wall to provide further protection for the citizens of the two cities. One interesting tower to note was named the Maiden Tower. During the Medieval period the tower was a prison for maidens who were easy in their morals. Another version goes on to state that the tower was constructed for maidens who refused to marry men chosen as their grooms by their parents.
