Adam Gebrian is a young architect and journalist who has a regular column in the newspaper Lidové noviny, so naturally a tour of “his Prague” included stops at a couple of the city’s most interesting contemporary spaces. But let’s start today’s show at what he considers the most vibrant spot in the Czech capital right now: the Náplavka riverside walkway beneath the embankment Rašínovo nábřeží. Over a beer at (A)void, a rusty old boat into a “floating gallery” with a great view, I put it to Gebrian that Náplavka can at times be extremely crowded.
