UNESCO - Independence Hall, USA

The Declaration of Independence (1776) and the Constitution of the United States (1787) were both signed in this building in Philadelphia. The universal principles of freedom and democracy set forth in these documents are of fundamental importance to American history and have also had a profound impact on law-makers around the world.

It was an interesting place to visit during my trip to the NE US some years ago. I remember taking some really nice photos but...then I also remember losing my camera on the very last day of the trip...how frustrating is that, right?  I found it pretty awesome that the visit was free, plus a very interesting presentation by the guide who leads you through the chambers.

Brooklyn Bridge, New York

The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City and is one of the oldest bridges of either type in the United States. Completed in 1883, it connects the boroughs of Manhattan and Brooklyn by spanning the East River. It has a main span of 486.3 m and was the first steel-wire suspension bridge constructed.

Interesting by-fact! Cable-stayed bridges date back to 1595, when first designs were found in Machinae Novae, a book by Croatian inventor Fausto Veranzio.

From my visit to NY last autumn, where I was more impressed by this bridge than anything else.
