History of Magic essay homework

Due to their close proximity, Hogwarts School of Wizardry and Magic and the town of Hogsmeade have a special relationship. One of the perks of having a magical town right outside of the school is the search for any and all secret passageways to and from each location. So far we know of at least eight passage ways to and from Hogwarts to Hogsmeade. All but two of the passageways were built for reasons unknown but it's possible that some of them were built in or around 1612 to be used during the goblin rebellion which centered in Hogsmeade. At least two of them were used in the final battle to defeat Voldermort.

There is one passageway from Hogwarts to a shop in Knockturn Alley in London. For the sake of completeness we will describe it here. The passageway is a link between two vanishing cabinets, one in the school and the other in Borgin and Burkes in Knockturn Alley. This link presumably worked until 1992 when Peeves (persuaded by Nearly Headless Nick) smashed the Hogwarts cabinet. The passage was reopened on or about December 1996 when Draco Malfoy fixed the cabinet. This passage is not shown on the Marauder's Map.

The first passageway from the school to Hogsmeade goes from Hogwarts third floor corridor to the Honeydukes cellar. To enter this passage from Hogwarts, one needs to tap on the statue of the one-eyed witch in the third floor corridor and say "Dissendium." It leads to a trap door in the floor of the Honeydukes cellar. The original Marauders found this passageway and marked it on the Marauders map. Fred and George, who also possessed this map, used it extensively when in attendance at Hogwarts and showed Harry how to use it.

The second passageway is from the Whomping Willow to the Shrieking Shack. It was built when Remus Lupin came to Hogwarts to allow him a place to go when he transformed every full moon. The tunnel is accessed by prodding a knot on the trunk of the Whomping Willow, and it leads to the basement of the Shrieking Shack.
The third passageway goes from the Room of Requirement to the Hog's Head Inn. This secret passage opened in 1998 to allow renegade Hogwarts students, Dumbledore's Army, who were in hiding to access food. Though the door is in plain sight in the Room of Requirement, the passageway can only be accessed from the Hog's Head through the portrait of Ariana Dumbledore on the second floor of the inn.

The fourth secret passageway is behind the mirror on the fourth floor and leads to a hallway in the back store rooms of Dervish and Banges. Fred and George used this passageway, which was unknown to Filch, extensively until it caved in winter 1992. This was a great way to check out the new magical equipment that was going on sale.
A fifth passage way entrance is located behind a statue of Gregory the Smarmy and leads to an opening behind an especially garish tapestry in Madame Puddifoot's tea shop. It's a favorite of trysting couples trying not to be seen arriving at the tea shop together.

A seventh passage way is located in the owlry on the Hogwarts grounds and leads to a underground passage that comes out right behind the Post Office of Hogsmeade. This passage was possibly used to smuggle out owls that needed to be seen going out as regular post instead of being sent from the grounds of Hogwarts.
The last two passage ways are lost to us. Only cursory mention of them is made in some of Filtch's papers as well as some cryptic notations in some of Tom Riddles notebooks.

One seems to have been in the "chamber" which we might assume means the Chamber of Secrets where the basilisk lived below Hogwarts. In such a maze of tunnels it is impossible to know where an entrance might be located. Though the entrance to the Chamber is still accessible through the bathroom on the second floor students are strongly encouraged not to attempt a search for this passage.

We only know about the last passageway as a full number of eight was mentioned in a History of Hogwarts written after the final battle. This last passageway is called "the eight" or sometimes "the final" but has never been confirmed or found by anyone in modern times.
