A wedding ceremony can be held both indoors and outdoors. It all depends on the type of ceremony you want to have. If you want a more intimate or low-key wedding, then it will be best to have the ceremony indoors. But if you want a more extravagant or full-blown event, then it is best to have the ceremony outdoors.
The wedding venue can also play a huge role in deciding whether to hold your wedding indoors or outdoors. If your venue is large enough and has an outdoor space, then it would be ideal for an outdoor wedding. However, if your venue does not have an outdoor space or has limited outdoor space, then it would be best for you to hold your indoor wedding there instead because of logistical reasons such as weather and noise levels.
