From this list, I’d have to say Roman, but the Celts and Vikings are very interesting, too! I’m not really into their religions, but the stories and learning about how they did things are very interesting. List of partially related nerd facts: [spoiler]Since we’re talkin’ ancient stuff, can I list some really cool old things about Austria? (Not Australia. It’s a country neighboring Germany.) The Vienna Zoo is the oldest zoo in the world, founded in 1752. Of course, gotta mention the Vienna Boys Choir founded late in the 15th century. Those kids are talented! The Austrian flag is the second oldest national flag in the world, being adopted sometime in the 13th century but in use during the 12th century. St. Peter’s is the oldest restaurant in the world. There are records of St. Peter’s being [i]mentioned[/i] as far back as 803 AD! Unfortunately, it doesn’t hold the record for being the oldest continuously running restaurant. (That title belongs to some restaurant in Spain.) They had to shut down when Napoleon rose in power. But guess what? [i]They came back[/i] and are still in business today! And, last but definitely not least, the salt mines of Hallstatt. Those mines have been producing salt for [i]7,000 years[/i]! Salt is still being produced, and some tunnels go as deep as 200 meters. Austria is a neat country :P[/spoiler]
