St Paul is about a 30 minute rail journey away from Minneapolis (which costs a whopping $1.75). It's the state capitol of Minnesota, and as such, is home to the State Capitol building, which has recently been restored. We got onto a tour, which was excellent, and saw some of the amazing work that's been done on the interior.
After the capitol building, we headed over to the Cathedral of St. Paul:
This is another incredible building that's well worth seeing if you're in the area.
On the way back, we stopped off at one of Minneapolis' many breweries for a spot of refreshment.
The next day, we rented some nice rides (equivalent to a Boris Bike in London) and cycled down alongside the Mississippi to Minehaha park, where one of the most photographed sites in Minnesota is located.
