The Crystal Ball/TAPS setup at MAMI is ideally suited to detect neutral and electromagnetic decays of the η and η′ mesons. In this contribution recent results on η and η′ decays from the Crystal Ball/TAPS experiment at MAMI are presented. These are the accurate measruement of η′ photoproduction cross-sections in the threshold region, the determination of the timelike electromagnetic transition form factors, and a test of low-energy QCD with the η → π0γγ decay. Finally, further perspectives are discussed.
