context_page_description: Carno is a village in Powys, Wales. The community, which is also a parish in the historic county of Montgomeryshire, comprises the townships of Derlwyn, Llysyn, and Trowscoed. It is in the geographical centre of Wales.
context_section_description: A Roman Fort named Gaer Noddfa is located next to the churchyard on the bank of the Afon Carno. The site encompasses a rectangular area 450 feet (140 m) by 270 feet (82 m). A large mound occupies part of the fort; pottery found nearby indicate medieval usage but suggestions that it was a Norman fortification like a motte have been rejected.
  In 952, Iago and Ieuaf, the two exiled sons of Idwal Foel, King of Gwynedd, invaded Dyfed. But they were defeated in a decisive battle near Carno by the sons of Hywel Dda, King of Deheubarth. The victory secured the sovereignty of North Wales. Another decisive battle took place here in 1081 in which "all the leading figures of the period took part, and which left its impress permanently on the history of Gwynedd and Deheubarth".
  A Grade II* 16th century timber-framed house, Plasau Duon, is near the village.
  The Manor House Plas Llysyn was a property raided as an LSD factory as part of Operation Julie. Plas Llysyn was under surveillance and the well that supplied the house was destroyed to investigate the contents. £500,000,000 of LSD was manufactured in the cellars here, supplying 50% of the worlds LSD at the time.
