Globular clusters can probe the formation history of galaxies by providing evidence for the chemical evolution and major episodes of star formation of their host galaxy. Elliptical galaxies are particularly important as they can form from a variety of channels, including formation at early times, major mergers, and accretion of smaller galaxies.

The giant elliptical NGC 5128 (Centaurus A), at a mere 4 Mpc away, gives us the only opportunity to study in extensive detail the globular cluster system of a recent merger galaxy. Situated in a small group environment, NGC 5128 shows visible evidence of recent accretions of its group members. To study its chemical evolution, we have obtained high-S/N spectroscopy of over 100 globular clusters in NGC 5128 with Gemini/GMOS-S. We have obtained ages and metallicities, as well as the level of alpha enrichment of the metal-rich and metal-poor globular cluster subpopulations. Recent kinematic studies and structural parameter measurements of the globular cluster system has also been performed using data of CTIO/Hydra, UT3 Melipal/VIMOS, and Clay/LDSS-2. These results to date will be presented and the formation history of NGC 5128 will be discussed.
