St. Mizan Church is an old church in Dublin. It was first built at the end of the 11th century. The existing church was built in 1686. The history of churches is quite interesting. The church was first built in 1905 by the Vikings who stayed in Ireland. Later, the church was rebuilt in the 17th century. In 1724, a huge organ was installed in the church. It is said that Handel's famous "Messiah" played here for the first time. But the most fascinating part of the church is the dozens of mummies in the basement. Initially, the mummies were stored in wooden coffins, but over time, the coffins gradually decayed and the air-dried bodies inside were exposed. Six of the coffin lids were completely decayed, so the mummies inside were completely exposed to people's eyes. Now two of them are open for public viewing. One of the most notable coffins in the basement is a separate coffin, whose owner is known as the Crusader. This "Crusader" is very tall, hands slightly up from the coffin, visitors can shake hands with this 800-year-old mummy, and you can touch it today.
