We present V and I photometry of the globu- lar clusters Terzan 9 and NGC 6453 for the rst time, and also of NGC 6139. The three clusters are projected towards the bulge. The Colour-Magnitude Diagram morphologies reveal that the sample clusters have blue horizontal branches. This characterizes an important fraction of the clusters pro- jected on the bulge, with implications on the early Galaxy history. From the colour-magnitude diagrams we derive red- denings of E(B V )=1 :95; 0:77; 0:70 and distances d 4:9, 9.4, 8.5 kpc respectively for Terzan 9, NGC 6139 and NGC 6453. We conclude that these metal-poor clus- ters are within the bulge volume.
