Calouste Gulbenkian Museum

Listen for a moment. Somewhere behind the trees, a duck lands on still water. The traffic of Lisbon's wide avenues fades into a low hum, and the air under the canopy feels a few degrees cooler. You are standing at the edge of one of the city's quietest gardens. Across the lawn sits a long, low building of grey concrete and glass. It looks almost modest. Inside it is one of the finest private art collections ever assembled by a single person.

That person was Calouste Sarkis Gulbenkian. He was born in 1869 into an Armenian family in Istanbul, then the capital of the Ottoman Empire. He trained as an engineer in London. Then he found his real calling... oil. In the early twentieth century, he helped broker the deals that opened the oil fields of the Middle East to Western companies. For his part in this work, he kept a five percent share. The press gave him a nickname that stayed with him for life — Mister Five Percent.

Five percent of that much oil made him one of the richest men in the world. And he spent much of it on art. But he was not a casual buyer. Gulbenkian studied every object. He consulted experts, compared prices, and waited for years when he had to. He once called his collection his children. He wanted only the best examples of each kind of thing, and he was happy to own fewer pieces if every one was exceptional.

So why is his collection here, in Lisbon? The answer is the Second World War. Gulbenkian had lived for years in Paris. In 1942 he moved to neutral Portugal and took rooms in a Lisbon hotel. He stayed for the rest of his life. He died in the city in 1955. In his will, he left his fortune and his art to a foundation based in Portugal. The Calouste Gulbenkian Foundation was created the following year, and it still runs this museum today.

The building you see opened in 1969. A team of Portuguese architects designed it, together with the landscape architects who shaped the garden. Notice how the two belong together. The galleries are low and horizontal. Large windows open onto the trees, so even deep inside you catch glimpses of green. This was a deliberate choice. The architects wanted visitors to rest their eyes between masterpieces — and to never feel shut inside a box.

Inside, the route is simple. It follows a chronological path, from the ancient world to the early twentieth century. The first rooms hold Egyptian art. Look for the small bronze cats and the carved stone heads. They are more than three thousand years old, yet the polish on the stone still catches the light. Then come Greek coins, Roman glass, and objects from ancient Mesopotamia, the land between the Tigris and Euphrates rivers.

Next, many visitors slow down. These are the rooms of Islamic art, and they may surprise you most. Here are Persian carpets with deep reds and blues, tiles from the Turkish town of Iznik, painted with tulips and carnations, and glass lamps once hung in mosques in Cairo. Gulbenkian grew up surrounded by this world. For him, these were not exotic curiosities. They were the art of his own childhood, and he collected them with special care.

Nearby, you will find Armenian manuscripts, Chinese porcelain, and Japanese lacquer boxes. Then the route turns west, into Europe. Here is a surprise many visitors miss. Around 1930, the young Soviet government needed money. It quietly sold paintings and sculptures from the Hermitage Museum in Leningrad, today Saint Petersburg. Gulbenkian was one of the buyers. Several works in these rooms once hung in the palace of the Russian tsars.

One of those works is a marble statue of Diana, the Roman goddess of the hunt, by the French sculptor Jean-Antoine Houdon. She seems to run on her toes, light and alert. Close by, the paintings include a Rembrandt portrait of an old man, his face lit against the dark. There is also a portrait by Rubens of his young wife, Helena Fourment. Take your time with both. The brushwork shows clearly up close.

Further along, the mood grows lighter. There are French tapestries, gilded furniture, and silver made for the courts of eighteenth century Europe. Then come the painters of the nineteenth century. You can look for works by Turner, Corot, Manet, Degas, and Renoir. Manet's painting of a boy blowing soap bubbles is a quiet favourite. It captures a fragile moment, the bubble about to burst, the child completely absorbed in it.

The final room holds what may be the strangest treasure of all. It is the work of René Lalique, a French jeweller and glass maker, and a personal friend of Gulbenkian. Gulbenkian bought directly from him for decades. The pieces here are dreamlike — combs, brooches, and pendants shaped as insects, flowers, and serpents. The most famous is a large ornament of a woman's body with dragonfly wings. Many visitors leave thinking about this room above all others.

When you step back outside, the garden is part of the experience too. Paths wind between bamboo, pines, and dense shrubs, past a pond and a small open-air amphitheatre. On weekends, Lisbon families come here to read, picnic, and walk. At the far side stands the Modern Art Centre, part of the same foundation, recently redesigned by the Japanese architect Kengo Kuma. It focuses on art from the twentieth century onward, much of it Portuguese.

Before you go, look again at the concrete walls. They are plain and grey, without ornament. Gulbenkian never saw this place. He lived his final years in hotel rooms, surrounded by his art. Now his collection sits in a garden, open to everyone. As you walk away, listen once more for the water, and the birds in the branches. Then the avenues of Lisbon return, louder and busier, just beyond the trees.
