Sorry if this is very obscure. I took this picture more than 12 years ago in Barcelona and I am finding it difficult to locate it. I think this were the letters RESTAURANT on a grass lawn, somewhere around the Museu Nacional d'Art de Catalunya or the Olympic Stadium.
I snapped the picture of N and a couple other letters (definitely R and T). I am finding trouble identifying it. I did not go in so I don't have any more pictures. Does anyone know where this is?
Edit
Some pictures before (timestamps ~ 12 minutes before)
And After (~25 minutes)
Now I remember, this metro was a bit weird that it went down really steep.
EDIT: apparently this is the Funicular de Montjuïc. Thanks to @jcaron.
