Andrés de Vandelvira — the cornerstone of the Andalusian Renaissance
In the 16th century, Andrés de Vandelvira, the genius architect of Charles V, transformed Úbeda's historic center into a Renaissance jewel. But behind the grandeur of the Sacred Chapel of El Salvador and Palacio del Deán Ortega lies a dark mystery: Vandelvira encoded a perilous secret in his designs—a conspiracy threatening the Spanish crown, concealed through symbols, measurements, and inscriptions only a sharp eye can decipher. Legends whisper that on his deathbed, he cursed the secret to remain hidden unless solved by the worthy. Rival factions still hunt for it today, from the shadows of Plaza Vázquez de Molina to the halls of Palacio de las Cadenas. Will you outwit them, crack Vandelvira's codes at 8 key landmarks, and expose the truth that could rewrite history? Start your quest now—time is running out before the enigma vanishes forever.

« « He made this city one of the most distinguished of its time. » »— Juan Agustín Ceán Bermúdez, art historian, 18th century (about Úbeda)
Úbeda's Golden Age: Charles V and the Master Builder
The 16th century was a period of splendor for Úbeda, under the aegis of Charles V, whose personal secretary, Francisco de los Cobos y Molina, was from the city. Wealthy and influential, de los Cobos undertook to transform Úbeda into a leading artistic and architectural center, symbolizing the power of the Empire. To do this, he enlisted the greatest architect of his time in Andalusia: Andrés de Vandelvira, a master whose work would profoundly mark the city's identity and challenge the grandeur of rival Baeza.
Born in Alcaraz in 1509, Vandelvira introduced the pure forms and classical grandeur of the Italian Renaissance to Spain, particularly in Úbeda. His achievements for Francisco de los Cobos, such as the Chapel of El Salvador and the Palacio de Vázquez de Molina, are masterpieces of balance and innovation. Vandelvira's influence extended far beyond these buildings, shaping Úbeda's urban fabric and overall aesthetic, which obtained the title of city from Charles V in 1540, confirming its privileged status.
