I will briefly review how multi-wavelength studies of distant galaxy
clusters can set important constraints on structure formation and
cosmology. I will then focus on new results on the mass distribution
in distant (z>1) galaxy clusters. Using deep HST and Chandra data with
extensive VLT spectroscopy is now possible to reconstruct the mass
density profile of both the dark matter and baryonic components of the
most distant clusters known (z~1.4). I will discuss how a systematic
study of the mass distribution of many massive clusters over 10-3000
kpc scales at varying redshifts, using complementary methods, can
provide stringent test on the LCDM paradigm and crucial input for mass
calibration in next generation cluster surveys.
