We visited the Vinh Moc Tunnels where an entire village sheltered from bomb attacks from 1965 to 1973. 

The memorial hall at the site is perhaps the most depressingly bad piece of architecture of the commemorative structures we’ve seen. It is so dreadful I’ve included a photograph of it above. It sits next to the discrete entrances to the tunnels which sit in a small grove of bamboo which slopes down towards the sea which you can hear. 

There is a lot of tourist ‘tat’ but this building sits on axis bluntly, with one of the tunnel entrances, asserting its importance over the historical subterranean structures it’s meant to mark.
