The eighteenth-century city of central Lisbon is known for its elegant design, proximity to the sea, and careful planning. This description applies within the boundaries of the old central triangle of hills, but not to the modern suburbs, some of which are grim. The Baixa, or lower town, was built in less than a decade by the Marquês de Pombal, a dictatorial minister, after the Great Earthquake of 1755 destroyed much of central Lisbon. The earthquake, which struck on All Saints’ Day in 1755, caused fires that raged throughout the city, and a tidal wave that killed 40,000 of the 270,000 population. Before the earthquake, Lisbon was one of the most active ports in Europe, having been prosperous since Roman times.

The city was twice at the forefront of European development and trade in the past, during the great Portuguese discoveries of the fifteenth and sixteenth centuries, and the opening decades of the eighteenth century, when Brazil yielded gold and diamonds. These were the great ages of Portuguese patronage. In the nineteenth and early twentieth centuries, Lisbon experienced political upheavals, but the Art Nouveau movement made its mark on the city. In recent decades, Lisbon has undergone significant reconstruction and renovation, boosted by EU funding for economic regeneration in the 1980s, its status as European City of Culture in 1994, hosting of the Expo in 1998, and the European Championships of 2004. The city’s transportation infrastructure has been improved, and historic districts and riverfronts have been given makeovers, making Lisbon one of Europe’s most exciting capitals.

Sintra is a charming Portuguese town situated within the cooling hills of the Serra de Sintra. With its undulating mountains, lush forests teeming with ferns and lichen, exotic gardens, and dazzling palaces, feels like a fairytale come to life. The town’s centre, Sintra-Vila, a UNESCO World Heritage site, is adorned with pastel-colored mansions nestled into verdant hills that slope towards the deep blue Atlantic.

The Celts venerated their moon god in Sintra, the Moors constructed a precipitous castle, and 18th-century Portuguese royalty strolled around its idyllic gardens. Even Lord Byron was entranced by Sintra’s beauty and described it in his epic poem Childe Harold’s Pilgrimage as, “Lo! Cintra’s glorious Eden intervenes, in variegated maze of mount and glen.”

While it’s a must-visit destination for those in Lisbon, many attempt to cram it into a single day trip, which can feel rushed. If time permits, Sintra is captivating enough to warrant a few days’ stay.

History of Lisbon and the Tagus Valley

Prehistoric Times in Lisbon and the Tagus Valley

The Lisbon and Tagus Valley region has a rich prehistoric history, with evidence of early human settlement dating back to the Paleolithic and Mesolithic periods. Archaeological finds, such as tools and cave paintings, suggest that early humans used the region’s riverbanks and coastal areas for fishing, hunting, and gathering. During the Neolithic period, the area saw the development of agriculture and the construction of megalithic structures, including dolmens and standing stones, indicating the presence of early agricultural communities.

Lisbon and the Tagus Valley in the Roman Period

During the Roman Empire, the region was part of the Roman province of Lusitania. The Romans established important cities such as Felicitas Julia Olissipo (modern-day Lisbon) and Scallabis (modern-day Santarém). The Romans developed infrastructure, including roads, aqueducts, and amphitheaters, many of which can still be seen today. Roman influence brought advanced agricultural techniques, viticulture, and the construction of grand public buildings. Lisbon became an important administrative and trade center within the Roman Empire, especially due to its proximity to the Atlantic Ocean.

Lisbon and the Tagus Valley in the Middle Ages

Following the fall of the Roman Empire, the Lisbon and Tagus Valley region was invaded by various Germanic tribes, including the Visigoths, and later the Moors. The Moors arrived in the 8th century and ruled much of the Iberian Peninsula, including the region, until the Christian Reconquista in the 12th century. The Alcáçova de Santarém and other Moorish structures are evidence of their presence. Lisbon was a significant city during this time, and its strategic location along the Tagus River made it a key site for trade and military defense. The Christian Reconquista led to the re-establishment of Portuguese control in the region, with Afonso I (King Afonso Henriques) reconquering Lisbon in 1147.

Lisbon and the Tagus Valley in the Age of Exploration

The 15th and 16th centuries marked a period of great expansion and prosperity for the Lisbon and Tagus Valley region, as it became the epicenter of Portugal’s Age of Exploration. Lisbon served as the hub for Portuguese maritime expeditions, which led to the discovery of new trade routes to Africa, Asia, and Brazil. The wealth generated from trade and colonial expansion funded the construction of monumental buildings, including the Jerónimos Monastery and the Tower of Belém. Santarém and other towns in the Tagus Valley also flourished during this period, benefiting from the region’s economic growth.

This period also saw the construction of iconic landmarks, including the Pombaline Baixa district, which still characterizes Lisbon’s downtown.

Following the Peninsular War and the Napoleonic invasions, Portugal underwent political upheaval, which culminated in the Liberal Revolution and the establishment of the Portuguese Republic. The Portuguese Civil War further shaped the region’s political landscape, with Lisbon emerging as the center of government.
