The construction of the world largest observatory for ultra-high energy cosmic rays was practically completed in 2008. However, since then several projects - aimed to enhance the sensitivity of the observatory in the region of lower energies - were proposed and are being realized.

In my talk I will briefly review the current status of the Pierre Auger Observatory and its recent results, and then I will introduce in detail these low-energy enhancements, namely projects of infill array of surface detectors, high-elevation fluorescence telescopes, and complementary array of muon detectors.
Prof. Ingo Allekotte is the Deputy project manager of the Pierre Auger Observatory.
