I visited this tentative WHS in Summer 2019 as a convenient stopover on my way to the newly inscribed Erzgebirge WHS.
Zatec has really made the most out of the regional and EU funds to exploit its main raw material for tourism. I'm glad I visited as I wouldn't have believed any information online that as much as seven fully-blown and rather large 'attractions' were linked to Zatec's hops, namely the Museum of Homolupolus, the Renaissance Malt-House Gallery, the Temple of Hops and Beer, the Peculiar Tramway Project, the Hops Astronomical Clock, the Hops Lighthouse and the Microbrewery U Orloje. Moreover, several house and building walls have been painted with hops motifs.
During my visit, I went up the modern looking Hops 'Lighthouse' (metal tower) to have a panoramic view of the whole hops town and fields and I checked out the microbrewery near the parking lot near a green area marked Zahrada. Even though I appreciate the noble attempt of attracting tourists in an otherwise ghost town of Czechia, I don't think that Zatec posseses any OUV even if it proudly claims to provide "the most important ingredient for the tastiest beers worldwide".
