Please identify this classic song/ soundtrack!!!

Hi!

I listened to this a lot of times and many people that listened to it said they already heard it but nobody seems to remember the artist or the movie this song could be from.

Please help me and identify the song of the following youtube video (the first few minutes): https://youtu.be/hYhRcaO8igU!

Thanks a lot!!!

Lovely track.
In the info section below the video, it says:
Music: "Allegretto from Palladio for String Orchestra" by Karl Jenkins/Carmine Lauri/David Alberman/London Symphony Orchestra
However, after searching google, nothing i found sounds like the piece in the video.
If you manage to find out what it is, I'd appreciate knowing.
If I find out anything, i'll let you know.
Good luck and best wishes
