Constitution Day and Citizenship Day is a single celebration that commemorates the formation and signing of the US Constitution while also recognizing both naturalized citizens and those born in the US. It"s a day to learn about these subjects, as well as a day many people become naturalized citizens in group ceremonies. (On average, about 700,000 people become US citizens every year.) To celebrate, we"re looking at an unusual close-up of the Statue of Liberty, a welcoming sight to immigrants and a symbol of freedom since 1886. The statue"s tablet has the date of the signing of the Declaration of Independence (July 4, 1776) inscribed in Roman numerals: JULY IV MDCCLXXVI.
