Walking from the station to the cathedral, you will pass this little souvenir shop where you can quickly hop in and buy something nice and/or special for the people back at home or even for yourself
There are a couple places near the cathedral that have postcard racks. One of them is a cafe that serves good gelato.
What to buy: Buy postcards because it is so difficult to photograph the sculptures and architectural details on the high exterior and the interior's labyrinth floor and stained glass windows.
You will also want to learn as much as possible about this fascinating cathedral's history so see if there are any books available in a language you comprehend.
What to pay: Come on, we're talking postcards for crying out loud! Definitely worth a pocket full of euro change.
At the West end of the cathedral itself is a small shop. Here tourist can buy sovenirs post cards and books. You can also get little gift items for friends.
Clementine sells "old world" charm. A lovely place to browse for that something special from yester-year.
