|Abstract:||We present UBV RI CCD photometry of three open star clusters Be 15, Be 71 and King 1 for the fist time. Base on these data, optical colour magnitude diagrams (CMDs) for the stars in the clusters down to V = 22 mag are studied. There are 1408, 1887 and 2485 stars located in the regions of Be 15, Be 71 and King 1 respectively. We also provide estimates of their fundamental parameters such as radius, reddening, distance and age. The radius values for the clusters Be 15, Be 71 and King 1 are 4.5, 3.0 and 4.0 arcmin respectively. The corresponding distances are 3.0+/-0.3, 3.9+/-0.4 and 1.9+/- 0.2 kpc respectively while the ages are log (age)=8.5+/-0.1, 8.8 +/-0.1 and 9.2+/-0.1 respectively. The red giant clump is clearly visible in the CMDs of cluster King 1|
