Alcazaba of Mérida
Built in 835 by Emir Abd ar-Rahman II as the first Muslim alcazaba in Iberia, this fortress was constructed to command Mérida after a local rebellion in 805. Its walls (130m long, 10m high) with 25 towers, its rainwater cistern (aljibe), and its inscribed military gate survive complete. Roman remnants beneath — a road segment, a dwelling, a section of Roman wall with a 5th-century buttress — reveal the layering of occupation. Today the former convent of the Order of Santiago inside houses the Junta de Extremadura's council chambers.

Badajoz (Alcazaba & Carnival)
Badajoz embodies the raiana (borderland) identity: its Alcazaba, fortified from the 9th century by Ibn Marwan and rebuilt by the Almohads in the 12th century, controlled the frontier between al-Andalus and the Christian kingdoms, and later between Spain and Portugal. The Torres de Espantaperros (1169), the statue of Ibn Marwan, and the ruins of a 13th-century church over a former mosque make the Islamic-to-Christian transition legible. The modern Carnaval de Badajoz (revived 1980, Fiesta de Interés Turístico Internacional) carries the suppression-and-revival pattern of Franco-era banning and democratic resurgence, with the Alcazaba as its backdrop.

Climb the Alcazaba walls for views over the Guadiana toward Portuguese Elvas, see the Ibn Marwan statue, explore the Archaeological Museum inside, attend the Carnival in February (one of Spain's largest), and walk the frontier corridor that shaped Badajoz's cross-border identity.
Old Town of Cáceres
Cáceres is the region's supreme continuity vault: UNESCO describes its architecture as 'a blend of Roman, Islamic, Northern Gothic styles' — layered heritage, not conquest-and-replacement. Thirty Islamic-period towers still stand (the Torre del Bujaco is the most famous); an aljibe andalusí (10th–12th century) with sixteen horseshoe arches survives beneath the Palacio de las Veletas; narrow labyrinthine streets preserve Islamic urban planning; churches sit atop former mosque foundations. The medieval Christian layer added noble palaces with horseshoe arches and inner courtyards that echo the Islamic aesthetic they replaced. Holy Week processions still move through these streets, and the cofradías that organize them are the custodians of ritual continuity.
