In this tropically abundant park spreading east of Av Insurgentes, paths encircle the Monumento a Álvaro Obregón, a monolithic shrine to the post­revolutionary Mexican president. The monument was built to house the revolutionary general’s arm, lost in the 1915 Battle of Celaya, but for some reason the limb was cremated in 1989. ‘La Bombilla’ was the name of the restaurant that once occupied this spot where Obregón was assassinated during a banquet in 1928. The killer, José de León Toral, was involved in the Cristero rebellion against the government’s anti-Church policies. In July, the park explodes with color as the main venue for Feria de las Flores, a major flower festival.
