ancient sort of designs and window types

I'd like to find references to certain types of objects, but, I don't know what particularly they are called, What do you call This particular type of architecture? and is there any name for the sort of curvy designs?

And what do you call this particular style of windows, this kind I usually recon seeing in castles of vampires in movies?

Solution 1:

The actual source for the first image is here, which explains that it's a 19th-century copy of the Gothic style.

Google's reverse image search shows the second is concept art for Halo 3. It doesn't seem to have anything to do with vampires, who tend to get either Gothic or Romanian. It reminds me of Ottoman, Persian, or Mughal, with their onionate tops, albeit nothing on Wikipedia looks quite right.

Solution 2:

The first is "gothic".

I don't know a name for the windows in the second: they look a bit art nouveau to me.
