Continental Europe's westernmost point

A lighthouse rose at Europe's westernmost edge

At the edge of the cliffs stands the Cabo da Roca Lighthouse, marking the westernmost point of continental Europe. Below it, waves break against granite cliffs over 300 feet high. The Romans called this headland Promontorium Magnum, the Great Promontory. Sailors in the Age of Sail knew it as the Rock of Lisbon, a landmark for ships working up the coast toward the capital.

The lighthouse itself began with an order issued on February 1, 1758, when Portugal's treasury board called for six lighthouses built along the coast to guide ships safely home. Construction here took over a decade. The light finally went into service in 1772, making it the third oldest lighthouse on the Portuguese coast, and the first one in the country built from the ground up rather than added onto an older fort or platform.

Romans worshipped sun, moon and sea on this headland

Further back still, before Sigurd's ships or any lighthouse, this headland held a different kind of beacon. The Romans called it Promontorium Magnum, the Great Promontory, and on a nearby rise called Alto da Vigia, they built an open-air sanctuary to Sol, Luna, and Oceanus, the sun, the moon, and the sea. Near the mouth of the Maçãs River, workers later found a Latin inscription dedicating a shrine to the sun and moon, raised by a legate of the province of Lusitania.

A Norwegian king conquered Colares for months

Long before any of that, this headland had already seen conquest. In 1108, during the Norwegian Crusade, Sigurd I of Norway took the region of Colares and held it for a few months. His fleet was sailing south toward the Holy Land, stopping along the Iberian coast to fight Muslim forces as it went. The occupation did not last, but it left this stretch of coastline in the records of a king who came from the other end of Europe.

Sand saved Colares vines when phylloxera struck Europe

The valley around Colares, inland from the cape, holds a different kind of history, one written in vines rather than stone. Grapevines have grown there since at least 1255. In the 1880s, a tiny insect called phylloxera wiped out vineyards across Europe, killing vines by attacking their roots. The vines in Colares survived because they grew in pure sand, where the insect could not move. Some of those vines are still growing on their own roots today, over 150 years old, making the valley one of the last places in Europe where the old-style, ungrafted vineyards never died out.

An earthquake shook the coast and spared some houses

On November 1, 1755, a massive earthquake struck Lisbon and the coast around it, followed by a tsunami that drowned parts of the capital. The shock reached Colares and the villages near this cape. Some buildings held. Casal de Santa Maria, a house built in 1720 from granite quarried in the Sintra mountains, survived intact. The parish church of São Martinho lost part of its roof and façade but stayed standing. Lisbon itself was not so fortunate; the earthquake and tsunami together killed tens of thousands of people across the region.

Earlier earthquakes near Lisbon, in 1151, 1531, and 1551, had already killed thousands and flattened houses by the hundreds, and a tsunami in 1531 drowned as many as thirty thousand people along the Tagus River. A smaller quake in 1807 killed eleven more. The ground under this cape sits on one of the most earthquake-prone coastlines in Europe.

The light went from oil lamps to electricity

By the mid-1800s, the simple light needed work. In 1843, the engineer Gaudêncio Fontana fitted the tower with a new rotating platform and sixteen oil lamps, each backed by a parabolic mirror to throw the beam farther out to sea. It worked for a while, but by 1865, critics called the system weak and old-fashioned. Ships still needed more warning in fog and storm, so the keepers added a steam-powered horn to cut through the mist.

The real change came in 1897, when the lighthouse went electric. A fourth-order lens and a turning mechanism replaced the old lamps, with a backup petroleum lamp standing by in case the power failed. A steam siren still sounded in the fog. Twenty years later, in 1917, a small building went up beside the tower just to make acetylene gas for a new lamp system.

Keepers automated the light and silenced its horn

Back at the lighthouse, the old steam siren gave way in 1932 to a horn powered by compressed air. Five years later, in 1937, a radio system went in, letting the lighthouse talk to ships and to the mainland. After World War II, the lamp changed twice more: first to a newer fourth-order lens, then to a stronger 3,000-watt bulb. By the late 1940s, the site finally got running water and drains, decades after the first keepers moved in.

The lighthouse stayed off the national power grid until 1980. Once electricity arrived, an electric siren went in two years later, in 1982. Automation followed in 1990, and the keepers who once produced their own acetylene gas saw that operation shut down for good. The electric siren itself fell silent in 2000, and the radio system switched off the year after. Today, three lighthouse keepers still staff the site, watching the light and keeping contact with the lighthouse at Ericeira up the coast.

A stone marks where the land ends

Cabo da Roca now draws visitors who come simply to stand at the edge of a continent. A stone monument near the cliff marks the exact coordinates, carrying a line of verse by the poet Luís de Camões calling this the place "where the land ends and the sea begins." The lighthouse still works, automated and unmanned most days, its beam reaching ships far out in the Atlantic. Quinta da Regaleira stands toward Sintra, with its mossy gardens and a mysterious initiation well, if the clifftop views leave you wanting more.
