Although the term iron curtain is the name of the boundary which divided Europe & wasn't a literal iron curtain, the Iron Curtain monument in Budapest is a really neat place to visit if you are into history. The iron curtain stands in front of the House of Terror Museum. Despite the curtain being a representation for the divide the weight, thickness, & cold iron of the chains sets an eerie and heavy feeling.
The monument has rather thought provoking quotes written on the sides. You can read a few of these below. It is definitely worth a stop and I have heard great things about The House of Terror Museum as well. The museum unfortunately was closing as we were strolling up to the monument. We spent time as well looking at the outside wall of the museum as too as it is a very interesting architectural piece. You can see what I mean for yourself HERE.
