Nuclear rings in barred spiral galaxies offer an opportunity to study starburst properties, as well as the evolution of star formation in the central regions of galaxies. To further our understanding in these areas, a large imaging survey of over 80 galaxies with previous evidence for the existence of nuclear ring structure has been performed in the Hα emission line and the B and I broad bands using the William Herschel Telescope. Here, we present images of a subset of these galaxies, which reveal well-resolved nuclear rings in Hα. The rings consist of numerous ``hotspots'' (i.e., Hα-bright star-forming regions). For each hotspot we calculate Hα equivalent widths and compare the results to population synthesis models to obtain age estimates. Typical cluster ages are no more than 10 Myr.
