A relatively short (2.5 km) but pretty interesting walkway through the historical part of Tallinn’s seaside that connects Linnahall area (where the starting point is located) with Seaplane Harbor Museum and continues a bit further to new Arsenal shopping center (which is pretty cool as well, as it was built in old military equipment factory premises).
Some time ago “Culture” in the name of the route sounded like a joke – thanks to graffiti covered ruins of old industrial buildings, ugly garages, railroad track remnants and all other kinds of odd post-apocalyptic structures on the route, but recently the biggest part of the route was seriously gentrified and turned to an ordinary town street. Generally, I would suggest to walk only the starting part of the route (from Linnahall to Kalarand Fish market and then proceed to Beta promenade (or Culture kilometer 2.0 as I would name it) – just check Betapromenaad article for the directions.
By the way, part of the route along Kultuurikatel has quite a rich history. For example, the meter-sized letters “UN” (you won’t miss it for sure) inscribed on an old electric plant’s chimney’s basement not far away from Linnahall represent a UN forces checkpoint as it can be seen in the famous science fiction movie ‘Stalker’ directed by Andrei Tarkovsky in 1979 (it was shot mostly in Tallinn and adjacent areas).
