The short verdict
Go, but go on the way to somewhere else. The dome is genuinely startling from underneath and the wartime story is one of the best on the island, and both of those are forty minutes of your day rather than half of it. Mosta is a busy ordinary town with traffic and parking to match, and there is very little reason to linger once you have walked back out of the church. Treat it as a stop between Valletta and Mdina, which is how the local tours route it, and it is excellent. Treat it as a destination and you will be standing in a square wondering what happens next.
What it actually is
The parish church of Mosta, built in the 19th century on a circular plan, with a dome that is regularly listed among the largest unsupported domes in Europe. Precisely where it ranks depends on who is measuring and what they are counting, so be wary of any page that states a confident league position. What is not in dispute is the effect: the interior is one enormous circular room and the dome simply sits above it with nothing in the way.
It is also a working parish church in the middle of a real town, not a ticketed monument. That changes the visit. There are services, there are locals, and it is expected that you dress as you would for any church in Malta.
The bomb
In April 1942, during the air raids, a bomb came through the dome while a congregation was inside waiting for Mass. It struck the floor. It did not explode.
Nobody was killed, and the event became one of the defining Maltese stories of the war. A replica of the bomb is kept at the church, and for most visitors it is the actual reason for the trip. Standing under an intact dome having just been told what came through it is a different experience from reading about it, which is the argument for going at all.
How to fit it into a day
Mosta sits in the middle of the island, which is its real advantage. It is on the natural line between Valletta and Mdina, and every organised tour that does both tends to stop here because the geography makes it free.
If you are driving, the church is on a busy junction and parking nearby is the usual Maltese experience. If you are on the bus, Mosta is a significant interchange, so it is easy to reach and easy to leave. Either way, budget the time for the dome, not for the town.
What is actually worth paying for here
Not the church itself. Entry to a working parish church is not where the money goes, though there can be a small charge for the associated display and wartime shelter.
What is bookable is the routing. Tours that string Mosta together with Mdina and Valletta solve the transport problem that makes Mosta awkward on its own, and the evening versions are the more interesting of them, because Mdina after dark is a genuinely different place from Mdina at noon.

Common questions
What happened with the bomb?
In April 1942 a bomb pierced the dome during an air raid, while a congregation was inside waiting for Mass. It hit the floor and failed to detonate, and nobody was killed. A replica is kept at the church.
How long do I need?
Forty minutes to an hour. It is one great room and a small display. Any itinerary giving Mosta half a day is padding the schedule.
Is the dome really one of the biggest in Europe?
It is consistently listed among the largest unsupported domes, but exact rankings shift depending on what is measured and which domes are counted. Be sceptical of a precise number. The effect from underneath needs no ranking.
Do I have to pay, and is there a dress code?
It is a working parish church, so entry to the church is not the expense, though there can be a small charge for the display and shelter. Dress as you would for any church in Malta: shoulders and knees covered.
Is it worth a special trip?
On its own, not really. Combined with Mdina, absolutely, and that pairing is fifteen minutes apart and the way almost every tour routes it.
