I find 3D paintings somewhat magical: the mastery of artists, a single precise focal point where it all comes together as intended by the author, and the true sensation of an illusion. In the cleanest, calmest, greenest neighborhood in all Riga, Mežaparks, a 3D street art festival is held every three years.
You might have heard of Mežaparks regarding other sightseeing destinations located there – the Riga Zoo or the grand stage of the Latvian Song festival. Mežaparks is literally a grand forest area veined with asphalt roads; the locals visit it daily and, on weekends, indulge in outdoor activities like roller-skating, bike riding, or taking a swim in Lake Ķīšezers.
Opt for all these activities like a local, and also see the work of the 3D festival. Take tram #11 or the Retro Tram, and once you arrive, be prepared: it is quite a distance, albeit enjoyable, if you decide to walk it. If the weather is nice, you can also rent a bike or scooter at the entrance.
To see the 3D street paintings, wander slightly off the main road and into the woods (follow the signs), and you will now (2020) see the result of the 2019 festival. Various topics include superhero movie characters alongside environmental hot topics – like the bees going extinct. The illusion fades away with time and winter weather conditions, yet the walk itself would be worth your while – a promise made by the capital of one of the greenest countries in the world.
