The 1917-1918 earthquakes destroyed many of the buildings along the boulevard, including the Reforma Palace. The southern end of the Avenida Reforma remained empty until 1935, when the Obelisco was built. Throughout the years, the Avenida Reforma has had several names; from its original name of "Boulevard 30 de Junio" it changed to "Boulevard Reformador", then to "Boulevard La Reforma", "Paseo La Reforma", and its current name of "Avenida Reforma". All of these names relate to the liberal reform of 1871.
