Untitled (Urban Wall) is an outdoor mural by Austrian artist Roland Hobart located at 32 North Delaware Street in downtown Indianapolis, Indiana.

[2] When the mural was completed, Marion Simon Garmel described Untitled (Urban Wall) as “a complex puzzle of rectangles, pie-shaped wedges, quarter arcs and S curves in bold but earthy colors”.

[2][4][5][6] Hobart's graphic mural is composed of bold geometric shapes of bright colors; mostly reds, yellows, and oranges with pops of blue, black, and white intermixed.

[3] The Urban Walls Project utilized painting services of the city's unemployed and youth to complete the selected murals.

[13] The parking lot which fills the space between the two buildings is owned by Richard L. Brown, Jr.[13] Since it was created in 1973, the mural has never been repainted and the north section has been completely painted over.

By 1977 the north wall of the mural had suffered damage from a water leak in the building which resulted in a call for its restoration, which never occurred.
