Blarney Castle is a medieval stronghold near Cork and, incidentally, the River Martin. Though earlier fortifications were built on the same spot, the current keep was built by the MacCarthy of Muskerry dynasty beginning in 1446. I did not kiss the Blarney Stone after hearing all the stories of how people have done disgusting things to it. The Stone of Eloquence (better known as the Blarney Stone) is located at the top of the castle, where tourists literally hang upside-down over a sheer drop to kiss the stone, which is said to give the gift of eloquence.
The highlight of the visit is strolling through beautiful gardens, which are spectacular even in the dead of winter. Blarney House was not open when we visited, but it is the more recently built (1874) mansion on the property.
