The Acueducto de los Milagros (Aqueduct of the Miracles) is a Roman aqueduct in Mérida, Spain. It was built during the first century AD to supply water from the Proserpina Dam to the ancient Roman colony of Emerita Augusta. After the fall of the Roman Empire, the aqueduct fell into decay and today it is in ruins with only a relatively small section of the aqueduct bridge standing. The Archaeological Ensemble of Mérida, including the aqueduct, was declared a UNESCO World Heritage Site in 1993.
Only a relatively small stretch of the aqueduct still stands, consisting of 38 arched pillars standing 25 metres high along a course of some 830 metres. It is constructed from opus mixtum – granite ashlar blocks interspersed with red brick – utilising a double arcade arrangement. The structure originally brought water to the city from a reservoir called the Proserpina Dam, fed by a stream called Las Pardillas, around 5 km to the north-west of Mérida.
It is thought to have been constructed during the 1st century AD, with a second phase of building (or renovations) around 300 AD. The aqueduct is preserved as part of the Archaeological Ensemble of Mérida, a UNESCO World Heritage Site.
In the immediate vicinity, a small Roman bridge called Puente de Albarregas runs parallel to the arcades.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
