Use the gold coin that is sparkling in the fountain next to the museum. You are looking for the Library Slip that is in a stack of books. You will next go to the castle, on the right side of which is the library. Go to the bottom aisle.
The dungeon appears if you click McM, after you got the library slip from Mordred's House/Museum. You can get the coin from the fountain, where it is shining.

In Mordred's house
In his house which is the one you first see, on the second floor. In order to look under the bed, you need the Princess note from her bedroom in the unreachable tower. (see related question)On the second floor of the Mordred Museum (his old house).
It is the first house you see on the island. It is Mordred's house, exactly as he left it when he fled the kingdom of Arturus twenty years ago. Get the gold coin from the fountain and look over the books in the Museum. At the entrance to the island, the far left side of the Village section. (Admission is just one gold coin!)
The museum is Mordred's house as he left it twenty years ago. Use the gold coin from the fountain to get inside. There is a library slip that refers to the Royal Library (in the castle, first floor right). (see related question)

Just tell the man at the front that you have the coin and he will let you look around.

The McM is on the bottom floor in the library. You can click on the mcm if you have the library card. The library card is in Mordred's house museum.
After the Astro Knights island release in June 2009, the next regular feature was Poptropica's Haunted House in October 2009. (Available through the Poptropica Store) The next scheduled island was Counterfeit Island.
The 10th island, not counting the Haunted House, is Counterfeit island. (see the related question) Haunted House was released after Astro Knights Island in late 2009.
The one coming out before it? Reality TV Island. But if you mean the most recent one to come out before it, then Astro Knights Island.
Use the gold coin (from the fountain outside) toi pay your admission, and look in the stack of books for a Library Slip. Once you have it, go to the castle library (castle first floor, right) and click the shelf marked Mc-M on the lower aisle. This opens the stairway to the dungeon.
