Here a good piece of advice before you visiting an interesting cemetery:
Casual clothes, good for the season. Choose sober colours.
Comfortable shoes: you have to walk a lot.
It’s a good idea bringing with you a little pack or a big bag where you can put:
a bottle of water,
snack, cookies, some chocolate, some fruit.
Perhaps you won’t have the lunch;
a copybook and some pens,
a hat and a little umbrella;
a smartphone;
lotion against the mosquitos; suntan lotion;
a camera.
Please, note that you need a permission if you would like photograph into an italian cemetery.
It’s very important you take with you respect and discretion: perhaps you are enthusiastic about your visit but you have to remember that here lays people beloved by relatives and friends.
