Sanatorium – spa hotel “Ordjonikidze” built in 1930s together with adjacent “Primorskaya” spa hotel (last 4 photos) are interesting places to visit in Sochi. You can have a walk in the parks and see the crumbling examples of Stalin’s time architecture.
Luckily both places are still open to public. There are many old trees, great views, no shops or cafes and a very special atmosphere.
