The Drake Municipal Observatory is an astronomical observatory in Des Moines, Iowa. It is jointly operated by Drake University and the city of Des Moines, and is located within the Waveland Golf Course between the 17th green and the 18th tee (the highest point in Des Moines at the time of construction). The observatory presents public programs on Friday nights throughout the spring through autumn months and, weather permitting, attendees can observe celestial objects with a variety of telescopes.

The main dome of the observatory houses an 8.25 inch refracting telescope, on a German equatorial mount. The ashes of the astronomer Daniel Walter Morehouse, and those of his wife Myrtle, are interred within the wall of the observatory rotunda.


The 8.25 inch refractor housed in the observatory dome was purchased from Warner & Swasey (with optics produced by John Brashear), and delivered to the university in 1894. Initially the telescope was housed in a dome atop the Science Hall on the university campus. This location was soon found to have been a poor choice; nearby trees and buildings obscured the horizon, and the vibrations produced by passing streetcars disturbed observations.

In the early 20th century a search was begun for a more suitable location to house the telescope, and a site on the Waveland Golf Course (nearly two miles west of the university campus) was chosen. The city of Des Moines agreed to provide the site and maintain the exterior of the building if Drake University would supply and maintain the observatory instruments, maintain the building interior, and offer public programs. The observatory building was constructed from Indiana limestone during the years 1920–1921, and was dedicated on November 5, 1921. At the time of its opening, the observatory housed a meridian transit telescope which was used to provide official time for the city of Des Moines (in addition to the main telescope in the dome).

Public Night Presentations

The main entrance

The observatory has public night presentations on Friday evenings during the spring through autumn months. A lecture on an astronomical topic is given at 8:00 PM, followed by observing with the historic 8.25 inch refractor, as well as an assortment of more modern small telescopes. Access to the observatory is not through the Waveland Golf Course's main entry; observatory visitors should drive to the site via Observatory Road, which originates on the west side of Polk Blvd, two blocks south of University Ave. Despite being located in the middle of a golf course, there is handicap parking adjacent to the building, and the building itself has been modified to be wheelchair accessible through the main entrance. The latest information on Observatory lectures is posted online.

Due to the Covid-19 pandemic, the 2020 public lectures have been held online.
