I was built between 1401–1410, between two old and distinguished towers – Köismäe and Epping. I was named after the tower chief Herbord Plate.
Occasionally I am argued over – whether I have the horseshoe-shaped cross-section that is common among the towers of Tallinn, or if my shape could rather be called circular. Well, from Laboratooriumi Street, on the edge from the city side, it is plain to see that one segment of my ring-shaped design has been cut out. I was in the hands of the military for a long time, standing empty and waiting for tenants. Occasionally, especially in the sum- mer, exhibitions are held on my first floor.
Construction history. A 24-metre-high, three-storey tower completed in 1410, with a diameter of 9.75 m.
