Orgosolo

In the centre of Sardinia, in the mountainous part of the island, there are lots of villages with a big murales tradition.
Orgosolo is one of the most famous. Murales are in private or public houses around the village , and generally have a strong social or political message. There're around 150 only in Orgosolo.
In this part of Sardinia people are really harsh and direct, with a big sense of honour and  proper rules. It's not a case one of the most important personality of the village is Graziano Mesina, a bandit famous for jailbreaking from prison 22 times (he succeeded 10 times).

Barumini

Around 1000 years B.C in Sardinia there was a civilization which used to build big and perfect fortresses of stones and rocks (just stones and rocks one over the other without any type of cement).
Some of them were extremely big, and around these buildings, called Nuraghi (Nuraghe is the singular), some villages flourished.
Inside the Nuraghe there were tunnels, rooms for praying (this civilization left lot of little statues of warriors and of  a pregnant woman symbolizing Mother Earth, that was their religion), for the old men council and many other things.
The complex located in Barumini, in Southern Sardinia  was under the ground until a Sardinian archeologist discovered it in the '50.
In 1997 was considered World Heritage by Unesco.
I've never been there, but who went there said it's a magic place.

Platamona

Platamona is commonly called the beach of Sassaresi (people from Sassari). Actually it's not a simple beach, but a huge coastal area. In the '50s and '60's it was quite a lively spot with concerts, night life and tourist resorts. Nowadays it's not fancy anymore, and it's considered  the beach where people from Sassari and the surroundings splash when they don't have lot of time and don't want to go to more fancy beaches (like in Alghero).
Actually the quality of the water is not bad, but because of so many beautiful beaches in the surroundings, Platamona has always been considered a 2nd class spot.
Anyway it's possible to reach Platamona by urban bus (takes around 15-20 minutes), and if you're up to, we can even have a walk in the pine tree forests in the area. There's also a little lagoon (called Pilo's pond!) where we can practise birdwatching.
Platamona is the perfect place for spending few hours in front of the sea without going too far.

Castelsardo

Castelsardo is a tiny town 30 Km far from Sassari, located in the north-western coast. Here just 5000 people live, mostly elder.
The downhill part is lovely, there is a little touristic harbour and some little cafes where old men read the newspapers and drink coffee. Typical mediterranean atmosphere.
But if you're up to walk uphill to the rock, you'll find yourself in the old centre, a little medieval pearl. Like in the real medieval cities, streets are steepy and narrow, but I guess Porto was a good training.
There's also a fortress, that offers you a wonderful view of the sea, but you can have a great view also from other parts of the cittadella.
In the old centre life is slow, you can find old ladies knitting in the street in front of their house and fishermen mending their nets.
From the castle there's an access to the sea, used in the past to get supplies when the city was under siege.
Nowadays this part is amazing: lot of grass in the middle of big rocks facing the sea and noisy seagulls will make this place perfect for a picnic or a little nap.
Castelsardo has been awarded as one of the best restored medieval  towns of Italy.

We could go there by bus for a day excursion, it takes an hour and on the way you have a great view of the north-western coast.
