There are over 300 individually landmarked properties and 52 local historic districts in Denver, which have been designated as such in order to encourage the preservation of the buildings and respect for the history of the Mile High City. Thanks to the National Historic Preservation Act, the subsequent Denver Preservation Ordinance, and the work of organizations like the Denver City Council and the Landmark Preservation Committee, we are able to enjoy these amazing historical landmarks in Denver which have been maintained or restored to their former glory for all to see. Here are just a few Denver historical sites that you'll definitely want to see:

1. Confluence Park

Confluence Park marks not only the junction of the South Platte River and Cherry Creek, but also the spot where the city of Denver began in 1858 when Green Russell and his prospectors began their search for gold.

2. Larimer Square

Larimer Square is Denver's oldest and most historic block. In fact, it was the city's first officially-designated local historic district! Its namesake, General Larimer, founded Denver City on November 22, 1858, and Larimer Street became the city's main street in 1861.

3. Union Station

Since its establishment in 1881, Union Station has been the central transportation hub and railway station for the Mile High City. It underwent a major renovation that was completed in 2014 and now houses fabulous shops, restaurants, and a luxury hotel.

4. The Oxford Hotel

Just a stone's throw from Union Station is the Oxford Hotel, the oldest and most historic hotel in Denver. It opened its doors in 1891 and has welcomed and wowed guests ever since.

5. Coors Field

The first official game at Coors Field was April 26, 1995, when the Rockies defeated the Mets 11-9. (Fun fact: Per the official Coors Field website, "In 1999, Coors Field firmly founded itself as the most prolific offensive ballpark ever created. The Rockies and their opponents combined for 303 home runs, the most ever in a season at one venue, with one or more tenants.")

6. Denver Performing Arts Complex

DPAC sits on 12 acres, contains 10 performance spaces, and is the second largest performing arts center in the United States. Its sculpture park is home to Jonathan Borofsky's The Dancers, a head-turning piece of art that stands proud at 60 feet tall.

7. 16th Street Mall

This mile-long pedestrian mall runs from LoDo's Union Station to the Civic Center Station Downtown and has remained a center for businesses and tourist attractions since its opening in 1982.

8. Daniels & Fischer Tower

One of the most distinctive landmarks in Denver is the Daniel & Fischer Tower, which was the tallest building west of the Mississippi River when it was built in 1910. It stands at 325 feet, has a four-sided 20-floor clock tower, and has a 2.5-ton bell above its observation deck.

9. The Brown Palace Hotel

Established in 1892, the Brown Palace is the second-oldest operating hotel in Denver and has lodged many important guests, including Elvis who declared it to be, "The best hotel in the world!" Modern-day guests can enjoy the incredible architecture of this historic building and its soaring views, all while getting pampered at the spa.

10. Colorado Convention Center

The Colorado Convention Center opened its doors in 1990, with its first event being the NBA Draft for the Denver Nuggets. Today it hosts more than 250 events annually and is home to another of the Mile High's most notable landmarks, the 40-foot-tall big blue bear (a.k.a "I See What You Mean").

11. Civic Center Park

This picturesque urban park opened in 1919 and continues to serve as the nucleus for Denver's government, arts, and culture. Civic Center Park is surrounded by many of the city's most prominent institutions.

12. Colorado State Capitol

The Capitol is one of the most eye-catching features of the Civic Center and has been in operation since 1894. The infamous gold leaf was mined in Colorado and added to the dome in 1908 to honor the Colorado Gold Rush. The interior contains White Yule Marble from Colorado quarries and what is believed to be the entire supply of Colorado Rose Onyx. (Fun fact: The 13th step leading to the west entrance is exactly one mile high.)

13. City and County Building

The final cornerstone of Denver's City and County Building was laid in 1982 after eight years of construction and is seen as the culmination of "a 30-year process to define the

Civic Center as the heart of city government and its cultural center." You might also know it as the Denver City Council Building. Tours are offered to take in the stunning architecture.

14. Denver Public Library

Denver built its first Central Library in 1910, and due to the city's continual rapid expansion, it has outgrown many facilities since then. The current Central Library opened in 1995, was designed by famed architect Michael Graves, and is a massive 540,000 square feet.

15. Denver Art Museum

Founded in 1893 as the Denver Artist's Club, DAM had many temporary homes before opening its own gallery in 1949 and has continued to expand to include three architecturally stunning buildings totaling over 350,000 square-feet. There are 10 permanent collections on display with over 70,000 works of art.

16. Denver Mint

The United States government established a mint facility in Denver in 1863, which served as an assay office where miners could bring gold dust and nuggets to be melted and cast into bars. Business boomed and the grand new facility that is now the Denver Mint was built in 1906. In its first year of operation, the Mint produced 167,371,035 gold and silver coins (valued at $27 million), and the current output today can exceed 50 million coins daily.

17. Denver Firefighters Museum

This 11,000-square-foot museum dedicated to the history of firefighting in Denver opened in 1980 and is located in historic Station One, built in 1909 and home of Engine Co. No. 1. Today the museum is regarded as one of the top three fire house museums in the nation.

18. Molly Brown House

Designed by renowned Denver architect William Lang and built in the 1880s, this house was once home to Titanic survivor "The Unsinkable Molly Brown." Today the building serves as a museum commemorating her life, as well as architectural preservation and the Victorian era of Denver.

19. Denver Museum of Nature and Science

The Denver Museum of Nature and Science was essentially conceived in 1868 when naturalist Edwin Carter began accumulating specimens of Colorado fauna and putting them on display in his log cabin. Word of Carter's collection got out and in 1900 The Colorado Museum of Natural History (now Denver Museum of Nature & Science) was founded. It gained a permanent home in City Park in 1908 and has continued to expand over the years to what is now a 716,000-square-foot complex with over 1,000,000 objects and artifacts.

20. The Buckhorn Exchange

The Buckhorn Exchange is Denver's original steakhouse and oldest restaurant and has been serving Old West fare since 1893 (as well as a few... unique big game menu items, like ostrich and yak). The building is overflowing with historical artifacts, including a 125-piece gun collection and a 575-piece collection of taxidermy. (You've got to see it to believe it!)

21. Red Rocks Ampitheatre

Red Rocks Amphitheatre is "the only naturally-occurring, acoustically perfect amphitheatre in the world." The first documented performance took place in 1906, and it's been rocking ever since.
