I have some videos that I made in the early 1990s that show various things of interest re Edinburgh.
This first one shows 6 buildings I visited back in 1993 on Doors Open Day - a day when buildings which are not normally open to the public invite visitors in for a look. Doors Open Day takes place on the last weekend in September.
The rarest one in the video is the old reservoir by the Castle which nowadays is a weaving centre. In 1993 it had just been drained and was waiting a new use.
Not sure what happened to the sound but it's not really needed.
