Bike week photo scavenger hunt

The national biking week was in May. The City of Oulu had a photo scavenger hunt, in which people were supposed to find locations shown in the photos. At the location you get a code word. Collect enough locations and you're in a raffle.  Most of the locations are well known and obvious, so anyone can easily get the required number of locations collected. A good way to get people on the bike.

There are four locations out of 12 locations that I've not found. Most likely they are in areas where I don't ride frequently, so I don't recognize them. Three of them are buildings. One is a tree, and I've not found the correct one yet. There is quite a lot of trees around here, so it might take a while. The correct results are available on the website and a quick search would tell me where they are, but that would ruin my fun. 

I had taken photos of four of the locations and most of them have been mentioned at the blog, too: a bike bridge, Hydro Dam Bridge, the combined heat and power plant, and the water tower (not sure if this has been on the blog?)

Recently I found the Sightseeing tower. Last week I took photos of the Chapel of St. Luke, a statue and Ouluhalli (an indoor sports arena). These were locations I knew and they're easy to find.

Now I have covered eight of the locations, with four to go. One building I think I can find, as the name of the building is on the wall. :-) I'm not sure if I can find any of the other locations left, as I have no means of looking at the photos provided as a clue. And I might not recognize the building if I'm looking from a different direction. I'll keep my eyes open, just in case.
