Texas landmark (5)
I believe the answer is:
alamo
'texas landmark' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for alamo that I've seen before include "Where Jim Bowie died" , "The red planet" , "Mexicans invested in Texas" , "ill-fated mission" , "Texas mission besieged and captured by Mexican forces in 1836" .)
