The remains of the Roman town of Regina Turdulorum, found near the municipality of Casas de Reina in Badajoz province, form an extremely interesting ensemble, in a perfect state of preservation, with the forum and a 1st century AD theatre as its most remarkable features.
The Roman theatre was built in the age of the Flavian emperors, could seat one thousand spectators and was operational until the 4th century AD.
Meanwhile Regina's Roman forum preserves the foundations of some houses, civil buildings, porticoes and the odd remnants of paving or Roman road that transport you directly to this period of history. A porticoed templum with a small room dedicated to the worship of the emperor and the imperial house has also been recovered through different excavations, alongside which other buildings must have existed, such as the market and the basilica.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
