Architectural Eclecticism and Urban Planning
The architectural appearance of Ibiza is a visual chronicle of Mediterranean history, where Punic foundations, Arab street layouts, and Catalan traditions overlap. Urban development is clearly divided into the fortified Upper Town (Dalt Vila), which historically served as a refuge, and the port districts that grew during periods of relative safety.
The Renaissance Era and Military Architecture
The city's dominant feature is one of the best-preserved examples of Renaissance military architecture in Europe.
- Style: Renaissance fortification style.
- Period: 16th century.
- Features: Massive sloped walls designed by Italian engineers (Giovanni Battista Calvi and Jacopo Paleazzo) to withstand artillery fire and attacks. The fortification forms a heptagon with seven bastions.
- Iconic Object: The walls of Dalt Vila. The main entrance — the Portal de ses Taules — is adorned with the imperial coat of arms and ancient statues, demonstrating the power of the Spanish Crown of that time.
Gothic and Baroque in Sacred Architecture
The city's religious structures demonstrate an evolution of styles, often combining a severe exterior (serving also as shelter during raids) with more decorative interiors.
- Style: Catalan Gothic transitioning into Baroque.
- Period: 13th–18th centuries.
- Features: Initially strict Gothic forms were eventually supplemented with Baroque elements during renovations.
- Iconic Buildings:
- Cathedral of Our Lady of the Snows (Catedral de Santa María): Built on the site of an Arab mosque. It features a trapezoidal Gothic bell tower and sacristy, though the interior was significantly updated in the Baroque style in the 18th century.
- Church of Santo Domingo: An example of 17th-century architecture with tiled domes, characteristic of Eastern Spain.
Traditional Architecture and Proto-Modernism
The unique "Ibizan style" was formed over centuries under the influence of the climate and a scarcity of materials, anticipating the ideas of modern minimalism.
- Style: Vernacular functionalism.
- Features: Cubic forms, thick stone walls whitewashed with lime to reflect the sun, flat roofs for collecting rainwater, and small windows to keep the interior cool.
- Influence: In the 1930s, this style attracted the attention of European modernist architects (such as Le Corbusier and Walter Gropius), who saw the embodiment of modern architectural logic in the simple white houses of Ibiza.
- Districts: The neighbourhoods of La Marina and Sa Penya. Here, a chaotic cluster of white houses forms a labyrinth of narrow streets descending from the fortress walls to the port.
Rationalism and Modernity
In the 20th century, the development of tourism brought new trends, which, however, attempted to fit harmoniously into the historical context.
- Style: Rationalism and modern resort architecture.
- Period: From the mid-20th century to the present.
- Features: The use of simple geometric volumes, glass, and concrete, but with respect for the island's traditional white palette. A major contribution was made by German architect Erwin Broner, who combined Bauhaus principles with local traditions.
- Iconic Objects: Casa Broner in the Sa Penya district — a striking example of 1960s modernism, now converted into a museum.
