Liscannor is a small coastal village in Ireland. The village's most notable contribution to the Harry Potter universe is the dramatic coastline of the Cliffs of Moher. These towering sea cliffs, which stretch for eight kilometres along the Atlantic coast, were transformed into the eerie setting for the Horcrux cave in "Harry Potter and the Half-Blood Prince". The scene where Harry and Dumbledore venture into Voldemort's secret lair is one of the most pivotal in the series.
Liscannor's quaint harbour is also featured in "Harry Potter and the Deathly Hallows Part 1". The scene where Hermione Granger erases her parents' memories was filmed here, adding a touch of real-world magic to this otherwise quiet fishing village.
