Narrative:
We were cleared the visual approach 22L while east of the field. We turned to a base leg and backed up the approach using the RNAV (rnp) Y 22L. Once in the turn we proceeded direct keeel on a heading of about 260 and I selected 2;400 feet on the MCP altitude window. Just short of keeel; tower issued a low altitude alert and told us to check our altitude. According to the fix page with 22L selected as a reference point; we were 6.3 miles from 22L and level at 2;400 feet MSL. My first officer read back our altitude and we continued the approach and landed uneventfully. Nothing further was said about the alert by tower. No egpws cautions or warnings were triggered.cleared the visual and well south of both the city and the RNAV Y 22L waypoints until keeel; I didn't feel we were grossly low on the approach. It would have been better to be closer to 2;800 feet at 6.3 miles out to maintain a 3 degree glideslope though. I was surprised to get the alert from tower. It was either an erroneous alert or one triggered due to the proximity of downtown chicago. In the future; I will be more careful to maintain a 3 degree glideslope throughout the visual approach to 22L at mdw.
