The University Park and Observatory Park neighborhoods are essentially one in the same. Bordered by I-25 to the North and Yale to the South in between University and Colorado Blvd., these neighborhoods were platted in 1886 after the University of Denver began to flourish. Small houses were built on large lots and the first house was constructed at 2525 Evans. Today most of the small houses in this neighborhood have been scraped and large new construction homes have taken its place. Although many small homes do still exist, the price to buy the land starts at a whopping $375,000!
