We present V, I photometry of the bulge globular clusters NGC 6380
and Terzan 12,
using the ESO NTT telescope. For the first time
colour-magnitude diagrams are obtained for these clusters, allowing
us to derive reliable cluster parameters. From the colour-magnitude
diagram morphology
both clusters result to be metal-rich.
For NGC 6380
we estimate , a
reddening of
E(B-V) = 1.07 and a distance
. For Terzan 12
we obtain
, E(B-V) = 2.06
and
.
