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 
. Using a variety of metallicity indicators in the optical and the infrared regions we determine a cluster metallicity ![${\rm [Fe/H]}_{\rm CG97}=-1.05\pm0.14$](/articles/aa/abs/2003/33/aa3755/aa3755_tex_eq2.png)
and ![${\rm [M/H]}=-0.83\pm0.14$](/articles/aa/abs/2003/33/aa3755/aa3755_tex_eq3.png)
. We find that Lindsay 1 has an age of 9–10 Gyr.
