Popis:	We present the results of deep high resolution imaging performed with ACS/HRC@HST in the most active region of the nearby starburst galaxy NGC 4214. We resolved the stellar populations of five Young Massive Clusters and their surrounding galactic field. The star formation history of this region is characterized by two main bursts occurred within the last 500 Myr, with the oldest episode spread out across an area larger than that covered by the most recent one. The ages derived for the analysed clusters cover a wide range between 6.4 Comment: 17 pages, 14 figures, accepted for publication by MNRAS
