The site was originally occupied by Ballyvaughan Castle, which stood right at the edge of the harbour. It was owned and occupied by the
O'Loghlen family, except for a period in the 16th century when the
O'Brians held it. In 1540, a stolen cow was found at the castle, and heavy fines were levied on the O'Loghlens—loss of cattle, goats, sheep and the town of Ballyvaughan. In 1569 the castle was attacked by Sir
Henry Sidney, but the O'Loghlens held on to the property. By 1840, the castle was in ruins. Only the foundations remain today. Three older piers had been built by the villagers, who used them for herring fishing. By 1831, turf from Connemara was landed here in great quantities, despite the shallowness of the bay. At that point, the town had 23 houses and 151 inhabitants. In 1837, to facilitate the turf trade, another quay was constructed, apparently also based on a design of Nimmo's. By 1841 the village had grown to 235 inhabitants and 35 houses. The new quay was of great importance, as it allowed Ballyvaughan to export grain, bacon and vegetables and to import supplies from Galway. For a while, Ballyvaughan was the official capital of this region of Clare, sporting a workhouse, coastguard station and large police barracks. Over time, as the roads improved and the piers fell into disrepair, the town lost its importance as a fishing harbour. More construction took place in the 1850s: in 1854, the old
National School opened, and the present Roman Catholic church was built around 1860. There was also a
Church of Ireland, but when this later closed, it was dismantled and re-erected at
Noughaval. In 1943, it was rededicated, and it is now in use as a Catholic place of worship (St. Mochua) there. By 1991, this had dropped to 184. ==Economy==
