Köismäe (Köismägi) 
Rope hill, named after the locality specialized in its manufacture, the German equivalent of which is Hamburg’s well-known Reeperbahn meaning “long, open space for rope-making” (MLG rēpærebāne composed of a) rēpære, sail-maker, and b) -bān(e), passage cut through a forest, or beaten path, or (long/wide), open space, only later evolving into today’s ‘station’. Curiously, mod. Ger. for ‘rope’ is Reep (from MLG rēp, sail) but used only by sailors today, while Seil, another more general modern term for ‘rope’ comes from MLG sēl but that also evolved into sēgel, or mod. Ger. Segel, sail. So the original ‘rope’ 'sail' is now rope, and the original , seems to have shifted meaning from sail to rope, as did ‘sheet’ in Eng. (see Soodi) (another word, Tau, later arrival than , ca. 1600)
cf. Old Dutch (8th C) reip, rēp ‘strip of land’
(see Suur-Patarei and Luite). The põik and tee have gone the way of all stone and all that remains is a tower in the old city wall.
