Using the Spitzer Space Telescope and Herschel Space Observatory, we haveconducted a survey of infrared galaxies in the field of the galaxy clusterAbell S1063 (AS1063) at $z=0.347$, which is one of the most massive clustersknown and a target of the HST CLASH and Frontier-Field surveys. TheSpitzer/MIPS 24 $\mu$m and Herschel/PACS & SPIRE images revealed that the coreof AS1063 is surprisingly devoid of infrared sources, showing only a fewdetectable sources within the central r$\sim1^{\prime}$. There is, however, oneparticularly bright source (2.3 mJy at 24 $\mu$m; 106 mJy at 160 $\mu$m), whichcorresponds to a background galaxy at $z=0.61$. The modest magnification factor(4.0$\times$) implies that this galaxy is intrinsically IR-luminous (L$_{\rmIR}=3.1\times10^{11}\ \rm L_{\odot}$). What is particularly interesting aboutthis galaxy is that HST optical/near-infrared images show a remarkably brightand large (1 kpc) clump at one edge of the disk. Our follow-upoptical/near-infrared spectroscopy shows Balmer (H$\alpha$-H8) and forbiddenemission from this clump ([OII] $\lambda$3727, [OIII]$\lambda\lambda$4959,5007, [NII] $\lambda\lambda$6548,6583), indicating that itis a HII region. The HII region appears to have formed in-situ, askinematically it is part of a rotating disk, and there is no evidence of nearbyinteracting galaxies. With an extinction correction of A$_{\rm V}=1.5$ mag, thestar formation rate of this giant HII region is $\sim$10 M$_{\odot}$ yr$^{-1}$,which is exceptionally large, even for high redshift HII regions. Such a largeand luminous HII region is often seen at $z\sim2$ but quite rare in the nearbyUniverse.
