"Umbral" is a collaborative exhibition by artists Manuel Álvarez Diestro and Karlos Gil, presented at the Central Library of Cantabria (Concepción Arenal Room) in Santander, Spain.

An interesting exhibition that can still be visited (opened on March 20 and open to the public until April 29, 2026), which is presented as a temporal journey in which you travel through underground architectural spaces in dialogue with the density of the contemporary city, exploring the coexistence of parallel worlds.

The exhibition brings together the world of architectural and landscape photography by Manuel Álvarez Diestro and the vision of Karlos Gil through his audiovisual piece "Origin." Throughout the exhibition, architecture becomes an immersive and perceptive experience, configuring a world reminiscent of science fiction and cinematic imagery.

The show features 30 works in various formats, including large-scale photographs of different Asian metropolises such as Seoul, Chongqing, and Hong Kong. At the center of the exhibition space is a structure called "La Jaima", designed by curator Arancha Vidal to project the audiovisual piece.

Project description by Manuel Álvarez Diestro and Karlos Gil

An Architectural Descent into a World of Pressure 
Karlos and I descended into the Madrid subway for the first time, almost like two explorers venturing into a hidden underworld. That experience stayed with us.

Later, in my city, Santander, a tunnel was opened connecting the beach area with the city center. I began photographing the Tetuán Tunnel almost obsessively, capturing the erosion of the rock, the humidity, and the materiality, and pushing the images toward a territory closer to science fiction than documentary.

At that moment, we felt it was necessary to connect these two worlds. Thus, UMBRAL was born: a journey into the underworld that, at the same time, engages with the architecture of ultra-dense buildings.

We incorporated works photographed in various Asian metropolises—Seoul, Chongqing, Hong Kong—building a climax of extreme density, where the architecture reaches a point of almost oppressive intensity.

We were interested in generating a sense of hyperbolic depression: a parallel world that exists alongside us, but of which we are rarely aware.

The exhibition brings together these two perspectives: the architectural and structural language present in my work, and the more introspective and unsettling vision of Karlos Gil.

In the center of the exhibition space, within a structure we call the tent, designed by curator Arancha Vidal, Karlos Gil's film ORIGIN is projected, adding a new layer to this descent.

The exhibition can be seen at the Central Library of Cantabria (Concepción Arenal Room) until April 29, with the support of the Government of Cantabria and curated by Arancha Vidal (Arte Peatonal).

Manuel Álvarez Diestro. Born in Santander in 1972, he is a designer by vocation, although his professional life turned around to a marketing and communications company. He loves the creativity,  innovation and the "Branding" of the big brands, which closely follows and is learning every day.

His passion rides between art and architecture and its way of expression is photography. He explores the city with his camera looking at urban landscapes to revitalize, through the image, the appreciation of cities, in their various developments. We can see these images in his latest works "New Cairo", "Pyramids," "Parabolic Facades", "Playgrounds of the World", "Souvenirs de Beyrouth", "Dystopic Songdo" and "Amphitheaters".

Karlos Gil born in Talavera in 1984. He studied at the School of Visuals Arts in New York and the School of Fine Arts in Lisbon and Madrid, where he obtained a doctorate in 2016.

His work is centered explores ideas of nature and its transformation over deep geological to explore the “otherness” of our surrounding world. His practice examines the complex and often contradictory ways in which human beings relate with the natural world, layering his artworks with encrypted stories from science fiction, occultism, underground culture, nihilism, mythology and industrial and biological evolution. His latest projects are conceived as scenarios that generate new possibilities of co-dependence between events and the objects they produce, always reflecting on a manifest impression of the “fall of time”, decadence, ruin or obsolescence of historical time.

He has had several international exhibitions in spaces like Centre Pompidou, Paris; HKW, Berlin; Witte de With, Rotterdam; NTU CCA, Singapore, Gasworks, London; Fondazione Baruchello, Rome; CRAC-Montbeliard; Galería Luisa Strina, Sao Paulo; MARCO, Vigo; CA2M, Madrid.
