Where is the world's only decipoint where 10 municipalities meet?

Similarly in Italy, the borders of ten municipalities meet at an undecempoint or undecipoint, at the summit of Mount Etna. These municipalities are Adrano, Biancavilla, Belpasso, Bronte, Castiglione di Sicilia, Maletto, Nicolosi, Randazzo, Sant'Alfio, and Zafferana Etnea. The territory of Bronte touches the summit of Mount Etna from two sides, making this multipoint one of elevenfold complexity, and thus evidently the most complicated geopolitical multipoint anywhere, other than the South Pole.

In Northern Ireland, ten townlands meet at a decempoint or decipoint at the summit of Knocklayd (clearly shown by Ordnance Survey mapping at point 311518 436392).[60][61][62] The townlands are, clockwise from north, Broom-More, Tavnaghboy, Kilrobert, Clare Mountain, Aghaleck, Corvally, Essan, Cleggan, Stroan, and Tullaghore.
