The VISCACHA (VIsible Soar photometry of star Clusters in tApii and Coxi HuguAy) Survey is an ongoing project based on deep and spatially resolvedphotometric observations of Magellanic Cloud star clusters, collected using the SOuthernAstrophysical Research (SOAR) telescope together with the SOAR Adaptive Module Imager. So farwe have used >300h of  telescope time to observe ~ 150 star clusters, mostly with low mass (M < 10^4M_) on the outskirts of the LMC and SMC. With this high-quality data set, wehomogeneously determine physical properties using deep colour-magnitude diagrams (ages,metallicities, reddening, distances, mass, luminosity and mass functions) and structural parameters (radialdensity profiles, size) for these clusters which are used as a proxy to investigate theinterplay between the Magellanic Clouds and their evolution. We present the VISCACHA survey and itsinitial results, based on our first two papers. The project´s long term goals and expectedlegacy to the community are also addressed.
