I present optical observations of the Blue Compact Dwarf Galaxy UM 462.
The images of this galaxy show several bright compact sources.
A careful study of these sources has revealed their nature of young
Super Star Clusters. The ages determined from the analysis of the stellar
continuum and 
are between few and few tens Myr. The total
star formation taking place into the clusters is about 0.05 
.
The clusters seem to be located at the edges of two large round-like
structures, possibly shells originated in a previous episode of star
formation. The sizes of the shells compare well with the ages of the
clusters. Evidence for the presence of an evolved underlying stellar
population is found.
