During our visit to Basel we went to de Munster of Basel, a beautiful church. It's located next to the river. There's no entrance fee, but if you want to climb the two towers you have to buy a ticket of 5 CHF. It's worth every franc! You can see all the sculptures really well and the view is amazing.
After all the climbing it was time to treat ourselves to something sweet and a drink. I love the music key on my latte!
