The Appenzeller Noble Memorial Museum is dedicated to Henry Gerhart Appenzeller, the missionary who opened the first Western-style educational institution in Korea in 1885. The school started with English and core subjects, but expanded into the Pai Chai University, Pai Chai High School, and Pai Chai Middle School and has many famous alumni, including Rhee Syng-man. The memorial hall opened in 2008 in the east wing of the original school building, which was built in 1916 and designated as a Seoul Monument. With dynamically arranged permanent exhibitions, annual special exhibitions and special lectures, the museum offers a unique learning experience to visitors and people with an interest in the history of education in Korea.
