Ayuntamiento de La Unión

Ayuntamiento de La Unión — the town hall of La Unión in Murcia — occupies Casa del Piñón, one of the most striking modernist buildings in the region. This is no anonymous 1970s municipal block: it's a restored turn-of-the-century mansion worth seeing even if you have no official business to attend to.

What will you see?

The building stands on the corner of Calle Mayor and Calle Jacinto Conesa, right in the heart of La Unión. It was commissioned by Joaquín Peñalver Nieto, a wealthy mining entrepreneur nicknamed "el Piñón" for his short stature. The design dates to 1899–1905 and came from the studio of architect Pedro Cerdán, one of the leading figures of modernist architecture in Murcia. Originally it wasn't a town hall at all — it was built as a purely residential property, combining luxury rental apartments with the owner's own home.

The façade brings together the ornate stucco work, wrought-iron balustrades and decorative flourishes typical of the modernist style with a solid, bourgeois scale meant to signal the founder's wealth. Inside, the standout feature is a metal dome whose design is attributed to Gustave Eiffel's workshop — an unusual detail to find in a building of this size outside Paris or a major capital. The building was listed as a Cultural Heritage Asset (BIC) in 1987, and a full renovation — the one that turned it into the seat of the town council — was completed in 2008 under architect Martín Lejarraga.

The visit makes most sense paired with a walk through central La Unión, a town whose whole urban fabric was shaped by the sudden wealth of the late 19th and early 20th centuries, when lead, silver, zinc and iron mining drew in capital and architects alike. Close by stands the Antiguo Mercado Público from 1907, an iron-and-glass market hall designed by Víctor Beltrí, now home to the Cante de las Minas festival.

How do you get there?

La Unión sits in the Murcia region, right next to Cartagena, with good road links and local public transport connecting the two. The town hall building is right in the town centre, so the easiest way to reach it is on foot from the old town's main streets — if you're driving, expect the parking limitations typical of a historic centre.

When should you visit?

As a working municipal building, access to the interior outside official hours is limited, so it's worth checking current opening times before you go. The best time to visit La Unión overall is during the Festival Internacional del Cante de las Minas, Spain's biggest flamenco mining-song festival, usually held in summer — the town comes alive with concerts, and its modernist architecture, the town hall included, provides a natural backdrop to the cultural events.
