Kynžvart was once significant castle, located at one of the highest elevations on the territory of the Czech Republic (827 m), used to stand near the famous Kynžvart Chateau of Austrian Chancellor Metternich. Its original name was Königswart (Royal Guard) as it was built as a border stronghold of the kingdom in the 13th century. The castle frequently changed its owners and it even served as a hideaway for thieves in the 14th century. The last owners were the Metternichs who did not repair the castle after it had been plundered by the Swedish army. Instead they used the ruins as building material for the construction of Kynžvart Chateau.
Today, remnants of the castle walls, the castle moat and the foundations of outbuildings are visible. You may enjoy a pleasant outing by walking to the castle ruins up the marked tourist path from Lázně Kynžvart.
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.
