Visitors to the Texas capitol building. The floor mosaic (more visible here) shows around its edge the countries that have flown their flags over Texas. They are:

• The Kingdom of Spain
• The Kingdom of France
• The Republic of Mexico
• The Confederate States of America
• The United States of America

In the centre it has the state emblem and ‘Republic of Texas’ because for about 10 years the place was a country in its own right. Apparently it has a provision whereby it can leave the US at any time too.
