You have seen this, haven't you?
It's a video made from a film said to have been taken in 1899 in Seoul. The picture above is not clear, but it does seem, however, that the city wall next to Namdaemun is tapering off, which would make it some time after 1907, when the walls were removed around Namdaemun and Seodaemun. It's not clear in this photo, or the film, that the wall is indeed missing, so it's still possible it was taken in 1899 (streetcars began running in Seoul in 1898).
A quick question: Does anyone know what gate it is we're seeing below?
As you can see, the film captures several different face
The site this video appears on says that it was taken by Elias Burton-Holmes. More information can be found about him here:
An American traveller, Elias Burton-Holmes, introduced film to the Korean royal family in 1899, and in June 1903 the first public screenings were held. These screenings were a part of entrepreneurial ventures by two American businessmen, H.R. Bostwick and Henry Collbran. A railway construction specialist, Collbran was appointed by Emperor Kojong as Manager of the Seoul Electricity Company and commissioned to introduce electricity and trams to Seoul. Emperor Kojong entrusted him with the electrification of Seoul because of local lack of experience, facilities and equipment. In order to maximise his profits, Collbran wanted to minimise the construction time. Therefore, he presented various public performances including wire-walking acts and dances of various sorts in order to encourage his workers. However, Collbran was surprised by the rapidly growing popularity of these performances. He therefore decided to make them a branch of his business, and this then led to the first public screenings.
