Stay:as per last night
We thought our spot was a too good to leave, so we stayed another day and didn't do too much. A few walks, lunch at the local tavern and read a book. We felt a bit out of our comfort zone at lunch. The waiter didn't speak English and luckily we met some fellow french motorhomers that were regulars who helped us with ordering. We chose a serve of roast pork that is enough for 2 and we washed it down with a couple of Bock beers. We had another lovely day.

Visited and stayed: Mina de Sao Domingos- free parking and services, lovely spot next to a lake. N37.672218 W7.504170
We didn't want to travel far today as it's a Portuguese long weekend and we didn't want to find ourselves struggling to find a spot to stay near the beach. So we chose the closest one with a service point and set off early as this is the best time to arrive when people are leaving in the morning.
On the way we felt we were driving along the Australian countryside with the gum trees everywhere.
Having got a great spot next to the lake, we went for an explore into the old mining village and disused mine area. Copper and sulphur was mined here for over 100 years from 1858 and the effects can still be seen today.
After a relaxing afternoon we had another walk around before dinner. Not an over complex day but it was lovely in its simplicity.

Visited:Beja and Mertola
Stay: Mertola - free parking, no service point, free water on the river N37.638890 W7.661120
We took the scenic route to Beja via Viana do Alentejo and then Vidigueira. It felt as if we were travelling on an Australian country road due to the gum trees everywhere. But as we drove through these villages it was definitely Portugal. 
On our way we passed many vineyards, olive groves and cork fields. This area has the largest production in both olives and cork.
We stopped in Beja and stretched our legs walking into the historical centre. It is the capital of lower Alentejo province. We saw the tower built by King Dinis and appreciated some tiled exteriors of some buildings, along with some other Moorish influenced churches. But all in all on a Sunday morning it was pretty uneventful.
From here we decided to head for an aire located on the river at the base of the interesting looking village of Mertola. There were lots of road works on the way and we must have missed the turn off. We took the next detour but we eventually realised that we were heading down a dead end country track. Doubling back we found the right road and felt lucky to get a spot in Mertola especially as it's a long weekend. We enjoyed a cooked lunch of schnitzel and ratatouille before relaxing and having a siesta. We then had an explore of the once inland port and the ruins around the castle.
