[Tagging] Postindustrial Castle

[Jaume Figueras i Jové]

Hi,

I've found a 'postindustrial' castle tagged [1] and I don't know how can 
it be correctly tagged. With 'postindustrial' I mean a castle build by 
one person during the last 40-50 years as its own personal project with 
no other means that its own personal.... I don't know why someone builds 
a castle nowadays. You can view a newspaper article [2] with a picture.

Now it is tagged as historic=castle, but is this correct?

TIA,

Jaume.
