Spectators across Spain watched in wonder, some whipping off their protective glasses and rising to their feet in unison, as a rare total solar eclipse swept across the north of the country on Wednesday evening, plunging it into darkness.

Spain deployed a massive police contingent and set up special viewing spots across rural areas that offered the best views of the spectacle.

Viewers in Buitrago de Lozoya, a rural district north of Madrid, clapped and cheered as the sky dimmed and Baily's beads – bright points of sunlight that shine around the edge of the moon during a total eclipse – glistened on the horizon just after 8.30 pm local time, lasting barely a minute.

"It's impressive how the colours return little by little after totality – first the reds, then the blues – just like at dawn and sunset, totally deceiving your brain," said economist Diego Fernandez, 32.

Rafael Jiménez, 50, a resident of Madrid, said the event felt like science fiction. "It was an absurd scene; we even got soaked when the garden sprinklers kicked in," he said. "And then, just like that, we were watching the sunset again."

Spain's turn with the eclipse followed shortly after a less remarkable spectacle over much of overcast Iceland, although a break in the clouds in the far west of the Nordic country allowed holidaymakers and locals a glimpse of the celestial phenomenon. The eclipse was hidden behind clouds in central Reykjavik although the darkness of the totality was still evident.

"It was like a whole day just came at once and I felt goosebumps because it just made us think about ... the shortness of life, how time can be different and it depends on your perspective," lawyer Eduarda Ortiz, 33, told reporters in the Icelandic capital.

Millions of people gathered in Iceland and northern Spain to witness Western Europe's first total solar eclipse in 27 years.

In Spain, authorities were expecting up to 6 million visitors in mostly rural areas under the eclipse's path across the north of Spain and the Balearic Islands.

The Iberian Peninsula last witnessed a total solar eclipse in 1912, but another is due on August 2, 2027, and an annular eclipse will follow in January 2028, completing the so-called "Iberian Eclipse Trio."

The uncanny sensation when day briefly turns to twilight and some animals fall quiet, while the moon passes directly between Earth and the sun, has often been seen through history as an omen of cosmic struggle or a sign of divine power.

For Spain, the event has been a chance to showcase its less-travelled regions and draw tourists from its overcrowded beach resorts. It also rolled out a large-scale police operation and public safety campaign to make sure the crowds did not set off wildfires.

The authorities dispatched 25,000 police officers to guarantee security around the eclipse observation sites and deployed nearly 100 planes and helicopters.

In Reykjavik, glasses that allow spectators to view the phenomenon without damaging their eyes have been sold out for days, as the country of roughly 400,000 people welcomed up to 80,000 visitors.

Totality reached Iceland's westernmost coast at about 5.44 pm, casting the far west of the island nation into total darkness for up to 2 minutes and 13 seconds.

The event has drawn both casual observers and "eclipse chasers," enthusiasts who criss-cross the globe to be in the path of totality whenever and wherever an eclipse occurs.

Gordon Telepun, a retired plastic surgeon and amateur astronomer from the US who has photographed six total eclipses, said he would watch from the island of Mallorca because Spain checked all the boxes for eclipse chasers. (Reuters)
