Paks Margareeta (0):

Fat Margaret. One of the city wall’s main cannon towers. A relatively recent name dating back to the 19th C, as a reminder of the wall’s founding mother, Margaret Sambiria, mother of Danish King Erik V Klipping (said to be thus nicknamed for his untrustworthiness and/or devaluing of coin) and fief-holder of Estonia (Domina Estoniae) from 1266-1282. Formerly known by the more prosaic runden tornn [...] vor den groten Strantporten [...], the round tower in front of the big beach gate (Suur Rannavärav). Used as a prison from 1830s-1917, now home to the Estonian Maritime Museum. See also Pikk Hermann.
