We present new CCD photometry of the Small Magellanic Cloud star cluster Lindsay 1 in UBVI filters. It is the first photometry in U and I filters. We determine the reddening E(B-V)=0.014. Using a variety of metallicity indicators in the optical and the infrared regions we determine a cluster metallicity ${\rm [Fe/H]}_{\rm CG97}=-1.05\pm0.14$ and ${\rm [M/H]}=-0.83\pm0.14$. We find that Lindsay 1 has an age of 9-10 Gyr.
