The architectural style of each church would depend on where you are in Nicaragua. In Leon or Granada, the typical Spanish churches were probably built in the 18th century. They are big and old with huge main doors. The facades are beautiful.
In Managua the church we had that looked like the ones in Leon or Granada was destroyed by the earthquake in 1972. The ruins of the church are still standing. However, the church itself is very unstable so it’s not currently being used. The only churches we have here in Managua are new and modern-looking. They are not that fancy and the altars are very simple.
In my opinion, the Nicaraguan Spanish service is less formal than the European or English service. I used to go to a Catholic church in the US when we were still living there, and as for what I have observed, their services are much more structured compared to the ones here in Nicaragua. The Catholic church service has been “tropicalized” here in Nicaragua. The service here in Nicaragua still follows the same pattern but for some reason, I think that in the US, the service is more formal.
There have been Jews in Nicaragua for a long time. Many of the more prominent family names in Nicaragua are Jewish. In San Juan del Sur, there is a small Jewish community. I just read about it recently so I don’t know much about it. For instance, I don’t know if they have temples there. In Managua, there’s also a Jewish community that has been around for decades. There’s a rabbi who comes here every year from another country for some of their important celebrations. That’s what leads me to believe that the Jewish community in San Juan del Sur is maybe from the US or that they speak English. Unlike in Managua, the Jewish community there is made up of younger people.
