We have presented g, r, B and V CCD observations of the halo globular cluster Pal 13.
The cluster is very sparsely populated and the horizontal branch is extremely peculiar. A sequence of candidates for blue stragglers can be seen on the color-magnitude diagrams.
An age of 
has been found using various methods.
This estimate puts Palomar 13 in group of so-called ``young" globular
clusters like Pal 12 (Gratton & Ortolani 1988; Stetson et al.
1989), Ruprecht 106 (Buonnano et al. 1990; Buonnano
et al. 1993), Terzan 7 (Buonnano et al. 1995b), Arp 2
(Buonnano et al. 1995a). Further photometry extended to fainter
magnitudes is necessary to confirm this.
