\title{Chandra Observations of Galactic Center: 
High Energy Processes at Arcsecond Resolution}

\begin{abstract}
About 2 million seconds of \chandra\ observing time have been devoted to
the Galactic center (GC), including large-scale surveys and
deep pointings. These observations have led to the detection of 
about 4000 discrete X-ray sources and the mapping of diffuse X-ray emission
in various energy bands. In this review, I first summarize general 
results from recent studies and then present close-up views of the
three massive star clusters (Arches, Quintuplet, and GC) and their interplay 
with the Galactic nuclear environment.
