Centennial is a city in Arapahoe County, Colorado. It covers 27.9 sq mi (72 sq km) and has a population of 101,000 (2011 estimate). The city is located at an elevation of 5,830 ft (1,777 m). It is the 10th biggest city in Colorado.

By any standard, Centennial is one of the youngest cities in the United States. It was only incorporated on 7 February, 2001, created for parts of unincorporated Arapahoe County. The residents of the area voted by a 77% for incorporation, based on a promise that city taxes will be kept at 1%. With a population of 100,000, it was the largest incorporation of a city in US history. Since it is so new, many people still are not aware of its existence, and mailing addresses still show Aurora, Englewood and Littleton, areas that are now part of Centennial.

Centennial was named after the nickname for Colorado, which is Centennial State, because it was admitted into the United States in 1876, the centennial year of the US Declaration of Independence.

Centennial is located to the southeast of Denver. It is part of the Denver metropolitan area. The city borders on Arapahoe County Airport, which has since been renamed the Centennial Airport (APA). The airport is bordered on three sides by the city of Centennial.

About this website



Dear visitor, thank you so much for reading this page. My name is Timothy Tye and my hobby is to find out about places, write about them and share the information with you on this website. I have been writing this site since 5 January 2003. Originally (from 2003 until 2009, the site was called AsiaExplorers. I changed the name to Penang Travel Tips in 2009, even though I describe more than just Penang but everywhere I go (I often need to tell people that "Penang Travel Tips" is not just information about Penang, but information written in Penang), especially places in Malaysia and Singapore, and in all the years since 2003, I have described over 20,000 places.

While I try my best to provide you information as accurate as I can get it to be, I do apologize for any errors and for outdated information which I am unaware. Nevertheless, I hope that what I have described here will be useful to you.
