Margam Stones Museum is a small Victorian schoolhouse near Port Talbot, which now provides a home for one of the most important collections of Celtic stone crosses in Britain. All originally found within the locality of Margam, and mostly assembled as a collection in the 19th century, they provide enduring testimony to a Welsh Christian culture between the 6th and 16th centuries.
The striking Cross of Conbelin is the most celebrated example. From around 1000 AD, it is a huge disc cross with Celtic interlace and plaitwork patterns, figurative scenes including a hunting scene, and inscriptions telling us who made it and who erected it. There are 17 early Christian stones, plus 11 memorials and other stones from the post-Norman periods. The museum is run by Cadw, the Welsh historic sites agency, and is close to Margam Abbey Church and the ruins of the Abbey buildings.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
