Abstract: Recent observations of two young star clusters in the Small Magellanic Cloud are presented. These clusters formed in very different environments 3–4Myr ago. NGC346 in the main body of the Small Magellanic Cloud contains ∼15 coeval subclusters and appears to be a good example of cluster formation via the collapse and hierarchical fragmentation of a giant molecular cloud. On the other hand, NGC602 is in a relatively isolated environment in the wing of the Small Magellanic Cloud and its formation was probably triggered by col- liding Hi shells. The dynamics of the ionized gas in the Hii regions associated with both clusters indicate that they are quiescent. This suggests that at the low metallicity of the Small Magellanic Cloud, the stellar winds from the cluster O stars are weak, and the nebulae are shaped by their ionizing radiation rather than their winds.
