Halfway between Porto and Madrid lies Salamanca, the home of the oldest university in Spain, a gorgeous cathedral and the best Ice-cream I have ever had! Salamanca is a gorgeous Renaissance town, consisting of old sandstone buildings that are a beautiful golden colour, however a lot of the buildings look the same so it can get a little disorientating, especially if you aren’t carrying a map. However there are signs and at some point you will find yourself staring up at the amazing Cathedral or Cathedrals, as there is actually two cathedrals, the old and the new, built side by side. Entry into the Cathedrals is €4 for a student, €4.75 adult and it includes an audio guide that directs you around the Cathedral. If you want to get through the entirety of the audio make sure you have plenty of time. The guide was really interesting, discussing the history of the region, the cathedral and the people buried in it. However it is very long and I have to admit I stopped listening at number 16 (there are about 35 stations, possibly more), but it is definitely worth a look.
