Google maps spotting

I had seen this weird looking place on Google Maps a long time ago. Now I had my camera with me and I decided to go and check this place out. Me and our friend Jolle took a tram and made it to Kallio, where this courtyard is located. We got in and it actually ended up looking better than on the satellite images I had seen.

Another cool little place that I didn't know existed in Helsinki. "Kallion tuubi" was found.
