The Ir(110) surface is studied by STM, assisted by LEED and AES. The clean surface exhibits a mesoscopic ``rippling'' due to formation of (331) facets, confirming former results. The ``ridges'' formed by the inclining and declining facets are up to several 100 Angstrom long in [1(1) over bar 0] direction and have an average width of approximately 40 Angstrom, resulting in a quite rough topography on a mesoscopic scale. At the top of the ridges a close packed double row separating the facets has been found. The Ir(110) surface is the only known fcc(110) surface that exhibits stabilization via (331) facets, whereas Au(110) and Pt(110) reconstruct in the (1 x 2) missing row structure with(111) facets.
