Herb (http://www.typophile.com/node/75367) is a wonderful typeface, but I'm not sure how well it could work as a display one.
What about a typeface that looks historical but actually isn't?

I'm talking about Hunyad / Hunedoara Castle in Hundedoara, Romania. Information about the castle: in English; in German (more detailed).

Please visit this page for other photos of the place.
We're looking for appropriate typefaces to be used for display purposes in a branding project. "Appropriate" could mean inspired from that era / matches certain motifs from the buildings / etc.
Here are two typefaces we're considering: JAF Herb and Harbour. Do you think these are appropriate for the period? Do you see any weaknesses in the way they are constructed? (I simply don't have the expertise to tell, so any help here would be very much appreciated.)
Feel free to add your own type suggestions. Thanks in advance.
PS: This isn't my project. I'm helping my brother with a bit of research for his final school project.
