Where did Eric propose to Donna on "That '70's Show"?

Eric proposed to Donna at the water tower on That '70s Show. The location was a fitting choice because the water tower had already become one of the series' most recognizable landmarks and a recurring setting for the Point Place teenagers.

Eric Forman and Donna Pinciotti had been close friends and neighbors before their relationship became romantic. Their engagement takes place during the show's fifth season, when Eric tries to make a major gesture despite the couple's uncertain future. The proposal reflects the show's mixture of genuine romance and awkward teenage decision-making.

The water tower is also associated with one of the sitcom's best-known running jokes: Kelso repeatedly falls from it. Earlier in the series, the gang climbs the tower to paint a marijuana leaf on its side. Donna later throws the engagement ring from the tower after becoming angry with Eric, connecting the proposal location to another major turn in their relationship.
