I will briefly introduce the present status of the ALHAMBRA Survey. ALHAMBRA aims at obtaining a map of 4 square degrees of the Northern Sky to an approximate depth AB(I)~26, through images in 20 optical medium-band filters plus JHK. Observations are carried at the Calar Alto 3.5m telescope, using both the optical LAICA and near-infrared O2000 imagers.More than 75% of the data has already been gathered, and the first internal catalogue is about to be released. This catalogue accounts for over two square degrees, with high-precision photometric redshifts (Dz/(1+z) ~ 0.02) for over 300,000 galaxies. Early scientific highlights include the determination of the galaxy luminosity function out to redshift 1.5 and its evolution, the search for EROs, the expectations for finding QSOs and AGNs in general, and a study of morphological/spectral evolution out to I~21.
