Kreenholmi manufaktuur was unmatched in Russia or Europe, employing over 10,000 workers amid Narva's roaring waterfalls. Though machines no longer run and workers are gone, its industrial architecture still impresses.

Tour starts at old gate (Joala 32), lasts ~1.5 hours, covers 2.5 km mainly outdoors through closed territory and old factory building including large weaving hall. Dress for weather. Language: Estonian. Free parking available.
