7 Days in Barcelona:
Gaudí's Unfinished Argument

You cannot prepare for the Sagrada Família. Photographs make it look like melting wax or a drip castle; in person it is something else entirely — a stone forest, the interior columns branching like trees into a canopy of vaults, the whole vast space flooded with coloured light through walls of stained glass tuned warm on the sunrise side and cool on the sunset side. Gaudí took over the project in 1883 and worked on it until a tram killed him in 1926, by which point only a fraction stood; he left behind models and the conviction that it would take generations, and he was right. It has been rising ever since, through war and poverty and dispute, funded by the people who come to see it, and it is only now — approaching the centenary of his death — nearing completion, the central tower finally topping out above the city.

To stand inside it is to feel the strangeness of the thing fully: a building begun before the car and finished after the smartphone, designed by a man who knew the work would outlive him by a century and gave his life to it regardless. It is the opposite of the tourist's checklist instinct, the urge to see-it-and-tick-it; the Sagrada Família is a hundred-and-forty-year argument that some things are worth starting even when you will never see the end. After a long trip built on moving on, on the next town and the next train, there is something quietly corrective about a place whose entire meaning is patience. Book a timed ticket, climb a tower for the view down the spires, and give it longer than you planned.

The cathedral is only the loudest statement of a case Gaudí made all over Barcelona. On the elegant Passeig de Gràcia stand two of his apartment buildings, and they are domestic architecture as pure imagination: Casa Batlló, its façade a shimmer of broken blue-green tile and bone-like balconies, the roof a dragon's back; and La Pedrera (Casa Milà), a grey stone cliff that seems to have been carved by wind, with a rooftop of helmeted warrior chimneys patrolling against the sky. Up the hill, Park Güell spreads his vision across a whole hillside — the serpentine tiled bench, the mosaic lizard, the columned hall holding up a public terrace with the whole city and sea laid out below.

The trip went looking, too, for the Gaudí the crowds skip: Bellesguard, a lesser-known house near the foot of the hills, a strange castle-like villa where the architect folded Catalan Gothic into his own organic language, quiet and almost unvisited. Taken together they make the argument plain — that buildings could grow like living things, that straight lines were a human imposition the natural world never agreed to, that ornament and structure could be the same act. Whether or not the traveller is persuaded by all of it (some of it tips into the overwrought), the ambition is total and the city is unimaginable without it. Barcelona is the only place on earth that looks like this, because one stubborn Catalan decided it should.

Beneath the modernist fantasy lies a much older city, and it is just as good. The Barri Gòtic — the Gothic Quarter — is a dense medieval maze of stone lanes, hidden squares and Roman remains around the great Cathedral of Barcelona (not Gaudí's; the older, darker one), with the soaring Santa Maria del Mar in the neighbouring El Born standing as the city's most beautiful church. Down the middle runs La Rambla, the famous tree-lined promenade — pickpocket-thick and tourist-worn, but opening halfway along onto the Mercat de la Boqueria, the riotous food market that is the city's stomach. For a quiet corner, Caelum serves coffee and convent-made sweets above the excavated medieval baths it's built over.

And the table is where Barcelona, like the rest of the trip, does its best talking. This is the city of pintxos and montaditos — at Quimet & Quimet, a tiny standing bottle-lined bar, the little open sandwiches built from tinned seafood and preserves are a thing of genuine art; at Xarcuteria La Pineda, a century-old deli-bar, the jamón and the vermouth come without fuss; Eldiset in El Born and the Michelin-starred Suculent mark the smarter end of the days. Somewhere in the week, too, the traveller did the thing travellers do at the end of a long road and got a tattoo — a small permanent mark of a thousand kilometres of Iberia, inked in a Barcelona studio and carried home under the skin. Not every souvenir fits in a bag.

For the last full look at the city, go up. Tibidabo, the mountain at Barcelona's back, is reached by an antique tram and funicular and topped by two things in odd, wonderful company: the great neo-Gothic church of the Sagrat Cor, its Christ figure stretched against the sky, and one of the oldest amusement parks in the world, a creaky century-old funfair whose Ferris wheel and little red aeroplane ride turn against the most enormous view in the city — the whole of Barcelona spread between the hills and the sea, the Sagrada Família's spires pricking up out of the grid, the Mediterranean going on forever. Nearby the Observatori Fabra keeps its century-old dome trained on the stars. It is the city's high quiet counterpoint to the roar below, and the right place to take the measure of a week.

And then the leaving, which on this trip came hard and early: out of the hotel at half past four in the morning, the Gothic lanes empty and echoing, a taxi through a city that for once was asleep, and the airport before dawn. A thousand kilometres of road — Porto to Mondim to Lisbon, down to the Algarve, across the plains to Évora and over the border, through the capital and Valencia and finally here — folded up and pointed home. The traveller leaves Barcelona the way the whole trip ran: still moving, in the dark, toward the next thing. The cathedral, behind, still unfinished. The road, ahead, still going.
