Hattorpe-tagune torn (0) 
The tower behind Hattorpe’s, a Hattorpe (van Hatdorp, fl. late 14th / early 15th C?) was listed in the 1410-1414 list of Tallinn tower chiefs, i.e. the ones with the keys (de de slotel hebben to den tornen). Das Bruderbuch der Revaler Tafelgilde (1364-1549) mentions a Tones Hatdorp (with standard variants: Tonnies, Tones, Toniges, Antonies, Anthonius [see Tõnu], van Hattorpp, and Hattorp) as a Tableguild brother from 1434, who might have been his son, hailing from Soest, Germany, source of many a later Baltic-German noble, and wealthy Hanseatic traders may well have kept two homes.
