Mértola Portugal Castle: Guadiana River Views & Serpa Fortress | Alentejo Day 5

Day 5 in Alentejo took me to Mértola, one of Portugal’s most atmospheric river towns, where a hilltop castle looks out over the Guadiana and quiet stone streets seem suspended in time. I explored the castle battlements, the hunting monument, the mural-lined river area, and then continued through open sheep-dotted countryside to Serpa for more fortress views and whitewashed Alentejo character. Join Jolly Good Journeys on this off-the-beaten-path day through southern Portugal, where castles, river light, and nearly empty streets create a side of Alentejo that feels raw, sunlit, and deeply authentic. From Mértola Castle to Serpa’s panoramic walls, this episode continues my Évora, Marvão, Monsaraz, and Estremoz road trip across Portugal’s hidden gems. ⏰ Video Chapters 00:00 Bom dia from Mertola Alentejo 00:10 Mertola Castle Guadiana Views 01:19 Mertola Hunting Monument 02:30 Mertola Murals & River Square 02:56 Serpa Sheep Fields Drive 03:29 Serpa Castle Panoramic Views 🔔 Subscribe:    / @jolly_good_journeys   🌐 Full Alentejo playlist:    • My Alentejo Road Trip: Exploring Ancient P...   #MertolaPortugal #MertolaCastle #GuadianaRiver #SerpaPortugal #AlentejoPortugal #PortugalHiddenGems #AlentejoRoadTrip
