It definitely was wheelchair accessible with two huge doors to open. I passed through quickly, so I don’t know about bathrooms.

It would be best to go to their website and check.

According to Wikipedia........ Bianchini's gnomon projects the sun's image onto his line just before solar noon, around 11:54 in late October Bianchini's sundial was built along the meridian that crosses Rome, at longitude 12° 30' E. At solar noon, which varies according to the equation of time from around 10:54 a.m. UTC in late October to 11.24 a.m. UTC in February (11:54 to 12:24 CET),[2] the sun shines through a small hole in the wall to cast its light on this line each day. At the summer solstice, the sun appears highest, and its ray hits the meridian line at the point closest to the wall. At the winter solstice, the ray crosses the line at the point furthest from the wall. At either equinox, the sun touches the line between these two extremes. The longer the meridian line, the more accurately the observer can calculate the length of the year. The meridian line built here is 45 meters long and is composed of bronze, enclosed in yellow-white marble.

Yes - that was the only English Mass advertised when I visited the Basilica. Best Peter
