We present 0.5 arcsec resolution optical images of the low-redshift, bright, broad-absorption-line (BAL) QSO 1700 + 518. We find a bright arc 2 arcsec to the NE of the nucleus which is redder than the surrounding host galaxy. There is also a faint radial structure to the SE, which is aligned with the core radio structure. The principal radio structure is a slightly resolved component coincident with the optical nucleus and an unresolved lobe 1 arcsec to the W which has no corresponding optical structure. We discuss the morphological and other properties of the QSO.
