LOS ANGELES (Reuters) -The Los Angeles City Council voted on Friday to launch a process to designate actress Marilyn Monroe's former home, where she died of a drug overdose in 1962, a historic and cultural monument, blocking plans to demolish the property. The motion to initiate consideration of the Spanish Colonial-style house in L.A.'s Brentwood section for historic preservation was introduced by Councilwoman Traci Park and approved unanimously the same day, according to her spokesperson Jamie Paige. The City Council motion itself also bars major alterations to the property while review of its potential status as a landmark is under way.
