Planning a trip to belgium

[bananamafia]

Hey everyone, im planning to take my dad to Belgium this year as it will be 70 years since his dad was there with the KOSB.
we will be staying on the outskirts of Deinze for a couple of nights and i wondered if anyone has any suggestions for WW1 WW2 sites/areas/museums to visit in the locality or within a reasonable drive?

Any pointers appreciated
