1. Bran Castle, in Brasov, is about 70 miles north of Snagov Lake, where the island monastery claims to hold Vlad remains, or did. Bran is about 87 miles north of Bucharest. Brasov gets tourists because Bran Castle looks good, is indeed a real and very historic castle, see http://www.draculas.info/travel_transylvania/bran_castle_history_i/, and is not far Bucharest's airport. It is located in a confluence of trade and military routes, defending against the Ottomans, and became wealthy with customs and other fees and duties.
2. Vlad's armies also attacked Brasov, but that did not relate particularly to Bran Castle. See the Draculas Info site. The Bran Fortress is pivotal to Romanian history in its own right: the incursion of Vlad tourists thinking this is pivotal Vlad does the castle a disservice, diminishing interest in real history.
Tours do hype the factoid that Vlad lived there. But it makes a buck - or lei, or the new leu. For the claims, see, for example.
- Claim: Bran castle was a residence of Vlad. See http://www.vsra.net/dractour/dractour
- Claim: Vlad used this castle as home base for his incursions from Wallachia, the southern part of Romania where he ruled from time to time, into the northern section, Transylvania. See http://www.draculascastle.com/html/branint1.
3. Vlad the Impaler and "Impalement"
Impalement: this was also a means of "crucifixion", see Crucifixion, history, uses, variations for etymology and more information than you want to know. The point is that the method was common. Did Vlad do more than most? Probably, or not? Takes more research than merely looking at woodcuts with agendas, making a point.
4. Return of property.
I read that the government is giving the castle back to the heirs, so it may or may not remain open as a tourist destination. Vlad or not, it is lovely.
5. Comparing history with legend
Some sites do a fine job of comparing the legends with the historical reality, as far as that is known or debated now. We took time to read the exhibits.
