Click below for underground-related photographs of Finland, visited 2019

1) P-Louhi car garage, Turku. Descends ca. 40 metres from entrance on Vasterlanggatan, below Taidemuseo, which is 40-50 metres above Vasterlanggatan, to Level 1. Has 2 levels, lowest up to 100 metres below ground level. Level 1 here, and here. There is a pedestrian exit from P Louhi, accessed up by a lift from the car park area Kauppatori Salutorget (Market Square) here.

2) Turku also has some short road tunnels through granite ridges, such as this one at Myllyande.

3) Turku also has some defensive works, probably of ca. World War Two vintage. They are aimed at defending the estuary of the River Aurajoki, which enters the Baltic just west of the city. Here, and here, and you probably don�t want to see the spider that span thatweb!!

4) The city also has some surface WW2-related defence works, concrete bunkers in the SW of the city, on high ground at Luolavouri, also once defending the Aurajoki estuary � lines of sight now largely blocked by trees and residentialblocks of flats. The bunkers have seen much attention from local graffiti artists. Pictures, here, here, here, here, and here.

5) Also some roads, e.g. here near Jyvaskala, have been adapted for possible military runway use in wartime.

6) More peaceful use of old bunkers in Kaarina, where a bunker, plan here (1), has been turned into an underground leisure centre, here, here, here and here.

7) Helsinki Metro is built very deep iin places, to get below the fjords, with a very long escalator serving this platform. Helsinki also has its share of road tunnels.

8) However the Finns have much older semi-underground storehouses, here and here. Also this old storehouse at Lappi, here, here, here, here, and here.

9) Finland is very �wired up� on the Internet and there are many roadside facilities such as here (1), here (3), here (4) and here (5).

10) Finland also has a large long-ter nuclear waste repository being constructed near Rauma, map and plan of the repository here. Source WIRED magazine, 21/4/2017, pp.119-127.

11) And if you want to drive here, here�s a shot of the Oresund Tunnel you�ll pass through on the way from Sweden.
