Gaudí vs Domènech i Montaner: Barcelona's Architectural Rivalry

Standing on the Avinguda de Gaudí in Barcelona, looking south toward the completed towers of the Sagrada Família and north toward the ornate brick and mosaic of the Recinte Modernista de Sant Pau, you are standing at the centre of one of the great architectural rivalries in history. Two architects, working simultaneously in the same Eixample neighbourhood, during the same decades, on different commissions from the same Catalan cultural elite. Two completely different answers to the same question: what should Catalan architecture be?

That question was not merely aesthetic in late 19th and early 20th century Barcelona. It was political, cultural, and deeply charged with the aspirations of a city and a region that saw in its architecture a form of identity assertion against a centralising Spanish state. Gaudí and Domènech i Montaner were not simply rivals in the market for commissions. They were rivals in the definition of a national project.

Who Was Domènech i Montaner?

Lluís Domènech i Montaner (1850–1923) is the architect most commonly lost in the shadow of his more famous contemporary, and this is a historical injustice that the quality of his buildings does not deserve. He was Gaudí's senior by two years, his professor at the Barcelona School of Architecture, and — by the assessment of many of his contemporaries — the more significant innovator of the two in the early stages of the Catalan Modernisme movement.

Domènech i Montaner wrote the foundational document of Catalan Modernisme: his 1878 manifesto "In Search of a National Architecture" predates any of Gaudí's major buildings and articulates, with remarkable clarity, the programme that both architects would spend the rest of their careers pursuing. He is the intellectual architect of the movement that Gaudí became the emotional embodiment of.

His major buildings in Barcelona include:

• Recinte Modernista de Sant Pau (1905–1930): the world's largest Art Nouveau complex, a UNESCO World Heritage Site, 850 metres from the Sagrada Família along the Avinguda that now bears Gaudí's name

• Palau de la Música Catalana (1905–1908): the other UNESCO site jointly listed with Sant Pau, a concert hall whose stained glass ceiling is one of the most extraordinary interior spaces in European music architecture

• Hotel España (1902–1904): a restaurant and hotel in the Raval neighbourhood, less well-known but containing some of the finest Modernista tilework in the city

All three are UNESCO World Heritage Sites. Domènech i Montaner is one of very few architects in history to have designed more than one UNESCO-listed building. His total is three.

The Specific Rivalry: Passeig de Gràcia and the Block of Discord

In the 1900s, a single block of Passeig de Gràcia — between Carrer d'Aragó and Carrer del Consell de Cent — became the physical site of the rivalry between the three leading Modernista architects: Domènech i Montaner, Gaudí, and Josep Puig i Cadafalch. All three built significant residential buildings on the same block within a few years of each other.

Domènech i Montaner's contribution was Casa Lleó Morera (1905) at number 35 — a richly ornamented building with ceramic tiles, stone carvings of natural forms, and stained glass windows that represent Modernisme at its most abundant. Gaudí's Casa Batlló (1904–1906) was at number 43. Puig i Cadafalch's Casa Amatller (1900) was between them.

The block became known, with affectionate irony, as the Manzana de la Discordia — the Block of Discord — a reference both to the conflicting aesthetic visions on display and to the three architects' different answers to the question of what Catalan Modernisme should look like. It remains one of the finest single blocks of early 20th-century European architecture anywhere.

Where the Two Architects Agreed — and Where They Diverged

Both Gaudí and Domènech i Montaner were Catalanist in their cultural politics, both drew heavily on Catalan Gothic and Romanesque tradition as the foundation from which to depart, both used ceramic mosaic and glazed surfaces as an explicit rejection of the grey stone austerity of mainstream Spanish architecture, and both believed that architecture could be a vehicle for cultural identity.

Where they diverged was in what each architect chose to prioritise after this shared starting point.

Gaudí moved progressively away from historical reference altogether, deriving his structural and formal vocabulary almost exclusively from natural forms — the branching tree, the catenary chain, the bone and shell. His late work is essentially without historical precedent. The Sagrada Família has no real architectural ancestor. It is something Gaudí arrived at by looking at nature for long enough that conventional architecture became irrelevant.

Domènech i Montaner remained more rooted in the vocabulary of medieval Catalan architecture, pushing its decorative range into unprecedented richness through the application of ceramic tile, terracotta sculpture, and polychromatic brick at a density no Gothic or Romanesque building ever attempted. His buildings quote history in every element while completely transforming what that quotation sounds like. The Palau de la Música's stained glass ceiling is simultaneously the most Gothic and the most completely unprecedented interior in Barcelona.

The simplest version of the distinction: Gaudí started from nature; Domènech i Montaner started from history. Both arrived, via different routes, at something entirely new.

The Avinguda de Gaudí: A Contested Memorial

The 850-metre pedestrianised boulevard connecting the Sagrada Família to Sant Pau was laid out in the original Eixample plan of Ildefons Cerdà in the 19th century, intended to provide a monumental approach axis to two significant public buildings. The boulevard was eventually named Avinguda de Gaudí — after one of the two architects whose buildings it connects, rather than the other.

Domènech i Montaner's Sant Pau is at the north end. The boulevard bears Gaudí's name. This is the rivalry in microcosm: both architects are present, both buildings are extraordinary, but one name is on the street sign.

In 2026, the Avinguda de Gaudí has taken on additional significance as a viewpoint for the completed Tower of Jesus Christ — the 172.5-metre central spire of the Sagrada Família, now fully visible from the Sant Pau end of the boulevard in a direct alignment that Domènech i Montaner would certainly have been aware of when designing his own building's main axis. The two buildings face each other across the boulevard, their visual dialogue exactly as planned by Cerdà's 19th-century urban grid.

Visiting Both in 2026: The Best Way to Understand Either

The most rewarding way to experience both architects is the same 10-minute walk that connects their buildings — the Avinguda de Gaudí from one to the other, preferably in the morning when the light is best on the Nativity Façade at the south end and still cool enough for comfortable walking.

The full walking route and the best stopping points along the boulevard are covered in our Avinguda de Gaudí walking guide, which includes the 2026-specific view of the completed central tower that no previous year of visitors could experience. And for the full Sant Pau experience — tickets, what's inside, and the 2026 centenary exhibition — our Sant Pau Recinte Modernista guide covers every practical detail.

For Sagrada Família tickets, SagradaFamiliaTickets.info is an authorised provider with real-time 2026 availability. The two buildings are best experienced on the same day — starting with the Sagrada Família for the morning Quiet Hour, then walking north along the avenue that separates and connects them.

For the full three-day Barcelona itinerary placing both buildings into a coherent day plan, our Barcelona 3-day itinerary covers the complete sequence. Getting to both buildings by metro is covered in our transport guide. To understand Gaudí more personally — the man at the centre of this rivalry — our Gaudí's death guide tells the story of his final years.

The Avinguda de Gaudí is entirely pedestrianised and free to walk at any time. Sagrada Família tickets from €26.00 through SagradaFamiliaTickets.info. Recinte Modernista de Sant Pau tickets from €17.00 at recinte-modernista.com. The two buildings are 850 metres apart — a 10-minute walk along a flat, historically significant boulevard.
