About Frogtown. Officially known as Elysian Valley, Frogtown got its name from the riverside ecosystem that included frogs. The neighborhood has a unique land use mix of light industrial buildings focused along the river and historic homes from the early 1900s. Over the years Frogtown has garnered a community of artists living and working among the light industrial workshops and homes. The annual Frogtown Arts Walk showcases this special community. Over the last two years, Frogtown has gained attention for being home to new restaurant concepts and for embracing the planned rehabilitation of the L.A. River.
