This is a rare and unexpectedly beautiful green space. A visit here allows you to discover where the plants landscaping Barcelona's green spaces for the last hundred years or so come from and how a plant nursery can also be a lovely garden.

This plant nursery lies on the north-west slope at the top end of Montjuïc, making the most of the terraces and banking to cultivate and store plants intended for landscaping Barcelona.
The oldest part has greenhouses, shade houses and spaces full of flower pots, while the new part has large terraces for plant stocks and plots used for experiments.
The Viver Tres Pins has an annual production of nearly 225,000 shrubs and perennials cultivated from cuttings and seeds, such as cheesewoods, crassulas, ivy, asparagus and privet, to name a few species. There are also two tunnels: one for producing plants and the other for conserving stocks.


This place was a picnic area at the start of the 20th century, known as the Font dels Tres Pins (after a fountain that still flows inside the nursery), where families would get together to spend a day in the open air or hold communal festivities, such as the “sardine burial”. In the 1920s it was turned into an area for supplying Barcelona with plants for the International Exposition of 1929. Later it was turned into the first municipal plant nursery producing plants for the city’s green areas and is currently the only one left in Barcelona.


There is an enormous variety of plant species here, which is only to be expected, given that the nursery stores the species that are intended for Barcelona’s green spaces. But there are other plants worth noting too that “landscape” the Viver Tres Pins.
The oldest part of the nursery boasts large specimens of Canary Island date palms (Phoenix canariensis), trees of heaven (Ailanthus altissima), white mulberries (Morus alba), sweet bays (Laurus nobilis), acacias (Robinia pseudoacacia), cypresses (Cupressus sempervirens) and elms (Ulmus pumila). Two trees in particular stand out for their rarity: a Chinese elm (Ulmus sieboldii) and a staghorn sumac (Rhus typhina). Another, a frankly enormous cheesewood (Pittosporum tobira), stands out for its size.
The trees embellishing the sloping parterres in the new part of the nursery are a good example of what you will find in Barcelona’s streets and parks. Here, among others, there are stone pines and Aleppo pines (Pinus pinea and Pinus halepensis), holm oaks (Quercus ilex), tipu trees (Tipuana tipu), pagoda trees (Sophora japonica), plane trees (Platanus x hispanica), purple-leaf cherry plums (Prunus cerasifera atropurpurea), Chinese weeping willows (Salix babylonica), hackberry trees (Celtis australis), acacias (Robinia pseudoacacia) and maidenhair trees (Ginkgo biloba).

Landscaping and Design

While the oldest part of the Viver Tres Pins still preserves the charm of the old plant nurseries and irrigation ponds used during the first half of the 20th century, the new part, which is much bigger, has a regular, orderly structure that is gradually encroaching up the mountain. It looks like a garden.
A wide road zigzags between the successive terraces, which are very large and finished off with grass-covered slopes, where a large variety of tree species grow.
The trees on the slopes and the plant pots which fill the terraces, especially those with flowers, offer visitors a colourful, vivacious and truly spectacular sight.
The nursery’s traditional irrigation systems have given way to other, more sustainable ones. Water from the grid has been replaced with Barcelona’s groundwater. This is pumped up to Tres Pins from the collection point below the Rambla and the nursery is also a groundwater storage and distribution point used for irrigating other parks and gardens on Montjuïc.

Art and Architecture

Towards the middle, more or less, of the new part there is a small strip on the path that is full of sculptures. This is known as the Petra Kelly Garden, after the German ecologist who was one of the founders of the Green Party in 1979. As you walk up, you will see a small terracotta sphere on the right, embraced by a female figure just as Petra Kelly embraced the Earth’s cause. It was put here on Earth Day in 1993, with Kelly’s favourite tree, a cherry tree, planted behind.
Just opposite, on the other side of the path, there is a small stone monolith dedicated to the another German, the sculptor Joseph Beuys, who incorporated the principles of ecology into his works. The monolith stands in front of a holm oak and next to one of the Tres Pins’ three most valuable trees, for its age and rarity: a showy honey-myrtle ( Melaleuca nesophila) some 500 years old.
