""If we're staying, we should put some protective enchantments around the place," she replied, and raising her wand, she began to walk in a wide circle around Harry and Ron, murmuring incantations as she went."

— Hermione Granger casting protective enchantments in 1997

Protective enchantments were charms used to protect an area for an extended period of time. The spells shielded specific areas, and could have a wide variety of applications, with many different types of protective enchantments existing.

History

Protective enchantments: Protego Maxima, Fianto Duri, and Repello Inimicum

There were many different types of protective enchantment with many different effects. It is unknown how old some of the spells were and who exactly invented them. The enchantments were used regularly during the Second Wizarding War in order for the wizarding community to protect themselves from Death Eaters and by Death Eaters themselves, so it can be assumed that they were used during the First Wizarding War as well.

The Vanishing Cabinets were able to bypass most protective enchantments, as a pair was used to penetrate Hogwarts Castle, which was heavily armed with magical protections, ancient and recently added.

During the 1988–1989 school year at Hogwarts School of Witchcraft and Wizardry, Professor Patricia Rakepick would often have her fifth-year Defence Against the Dark Arts students demonstrate the correct casting of protective enchantments at the start of each of her lessons.

Casting

"Harry strode off through the heather, walking in a large circle with the distraught Hermione at its centre, casting the spells she usually performed to ensure their protection."

— Harry Potter casting various protective enchantments during the Horcrux hunt

In order to protect a certain place, the caster had to repeat incantations of charms over and over in the area they wished to protect. The spells circled the area and created a light effect similar to a heat wave around the protected area.

Behind the scenes

• In the video game adaptation of Harry Potter and the Goblet of Fire, the dome effect that happened during Priori Incantatem is not seen. Instead Voldemort uses the spell to distract Harry while his living skeletons and his paternal family's grave attacks him.
• In the Nintendo DS version of the video game adaptation of Harry Potter and the Deathly Hallows: Part 2, the protective enchantments had to be cast from certain defensive shield locations.
