A snapshot of Riga, Part 3(Final)

Here it is, the last of my posts about Riga(for now). Here’s an overview of the different places I mentioned(plus the ones I will mention today) Todays post includes a bookshop, a free tour, and something that boggles my mind.

Roberts books
To all the book lovers, especially those who like reading in English, Roberts books is the place to go. A short fifteen minute walk away from the old town on Dzirnavu Street 51, in a small alley, this second hand bookshop is quite easy to miss. The outside of the shop is nicely decorated, and once you’re inside two rooms filled with English books are there to greet you. Surprisingly, it is about as big and as well stocked as any second hand bookshop in a native English country. The soft music, nice interior and yellow lightening make it easy to immediately feel content and just curl up on one of the comfy chairs with your newest discovery.

Yellow suitcase free tour
If you’ve been to Tallinn you might have heard of the yellow suitcase tours before. The ones in Riga claim that they were first, but who knows! Either way, this free tour is run by young locals and gives you a completely different take on the city. Instead of just showing you what every tourist knows they share interesting stories about parts of the city that might otherwise be easily overlooked. The tour starts every day at 12 in front of the St. Peterschurch and lasts for about two and a half hours.

Something that you’d walk past easily (and that I’m still breaking my mind over)
In the park surrounding the city canal, opposite of the National Opera, there is a flower bed(when I was there it was without flowers). Now this might not strike you as odd, and I would’ve walked past as well, it if it hadn’t been pointed out to me during the Yellow Suitcase tour. The flower bed is ringed by flat stones, in a perfect circle and in the middle of the dirt in this flower bed, is a flat round stone. “Stand in the middle and just say something” is what we got told. Surely enough, when others did it nothing really happened, aside from the surprise you would see registered on their face after speaking their first word. Soon I found out myself, the flower bed plays a weird acoustic trick, making it sound like you aren’t standing outside in the open air, but in a small glass dome placed on top of the flower bed. It only seemed to work if you were standing on the flat stone in the middle, but outside the flowerbed your voice would be heard normal without any acoustic effect (Standing with two worked as well, only when we were with 4 and not talking towards the outside of the circle, would the acoustics be less – The geek in me obviously immediately thought about other dimensions, force fields and all that Doctor Who induced stuff.)
Ofcourse I have my own logical thoughts about how this could work(My mind doesn’t just go “Aliens”), but I’m very interested to hear your opinion about how you think this works!! If you know excactly how it works, even better!
