Goteborg has very short dark nights in the summer, but as I visited Goteborg around Easter time I still had the chance to see the city illuminated. Especially the sights along the canals are well worth seeing in darkness.
Apart from that, the Scandinavian sky often offers a very nice atmosphere at dusk. So don't forget to bring your camera ....
Goteborg has many interesting buildings constructed in various architectural styles. You can find buildings from the 17th century (e.g. Crown Fortlet) as well as modern buildings like the Opera House (1994). Many houses in the suburbs of Goteborg were built in functionalism style at the beginnig of the 20th century.
I really like the Neo-Gothic Main Train Station (Central station) which was completed in 1858. So always keep your eyes open when wandering around Goteborg.
Favorite thing: One thing I noticed while walking around Goteburg is that it is almost like a big outdoor art museum! Everywhere you look in the city centre there seems to staues, modern art sculptures etc dotted about - from the massive statue of Poseidon to small busts and more modern sculptures like this one near Norra Allegatan...
I assume this wall mural was maybe in recognition of Goteburg playing host to the World Athletic Championships, I think it was in 1995 but could be wrong. I remember watching at home when Jonathon Edwards broke the triple jump world record & the 18 metre barrier!
Anyway there was a stadium just up the road from where I saw this so maybe that was where they were held.
I just have a thing for wall murals though!
Göteborg puts a lot of effort into design of street pavements. They are usually various stones, with longitudinal stripes of stone as a landmark (very useful if you're pulling a bag or a suitcase on wheels :).
Pedestrian areas and bicycle lanes are carefully designed and bordered. Almost always street pavement is continous while asphalt of side-streets stops there, marking the area where cars are allowed to cross but are not generally wellcome - the priority is given to pedestrians.
You must take the time to walk the city. It is very centralized unlike Stockholm and there are so many undiscovered areas. You should also definetly see Gamla Stan there.
Fondest memory: My favorite memories of Göteborg invlove walking around the city in the lovely sun, eating an ice cream while sitting and people watching.
Start your day by walking to 'Skansen Kronan'. From here you can look all over the city and make you a picture of how the city looks like. Then you walk to 'Linnégatan' a street where you will find a lot of café. Stop and enjoy a cup of coffe, why not stop att 'Bönor och Bagels'/'Beans and Bagels'. After a short brake, start walking towards a park called 'Slottskogen'. Walk straight through the park and cross the motorway on the left and walk into a garden called 'Botaniska trädgården'. Walk too the top of the garden. Here you will find a gate. Open the door and now you are in a forest called 'Ängsgårdsbergen'. Follow the sign to 'Asia'. Walk to the top of the mountin. Look out over the city and then walk back again. When you find yourself outside 'Beans and Bagels' again. Start looking for a nice restaurant. This is what i would have shown you. No shopping, no museums etc etc...
Fondest memory: Enjoying a really good espresso in the sunshine...
Goteborg is not a very large city so I would recommend that you walk around.
When I was there, I spend the whole day walking...
Just go to the Tourism Office and ask for a map.
Favorite thing: You can see the floating Barken Viking Restaurant here. The ship is huge, so probably about 1,000 people can dine in.
