The Castle of Ayora was built probably in the mid-13th century, after the Reconquista, on the site of an ancient Arabian fort. The architectural ensemble was composed of the four-storey residence-palace, two fortified towns, and one large keep, as well as other rooms for the soldiers and serfdom, aljibes (European Middle Ages castle cisterns that collected the rain water to provide drinking water to the castles) and gardens. This was surrounded by around 1,000 m of defensive walls and defensive towers.
The castle was reduced to ruins by the troops of Philip V of Spain, in the War of the Spanish Succession, but its profile and its vast size are still noticeable. The keep, of square plan, the Puerta Falsa (Fake Door), commissioned by the Marchioness of Cenete in the 16th century on which it was her coat of arms, as well as paintings, defensive walls, buckets, moats, and cisterns, stand out in the remains of the castle.
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.
