“A weekend trip out of the city!”
At this time of year, Ba Vi National Park  is most famous for its da quy flowers, which bloom in the first few  weeks of December. In the evenings the road leading to the top of the  mountain is claustrophobically busy, with visitors lining both sides of  the road to get a snap or three of the yellow flowers before they  disappear for another year. 
I decided to visit Ba Vi for another  reason, one that is perhaps less well-known among the expat community,  despite an obvious link to our history in Viet Nam. To avoid the crowds,  I headed there at dawn, to make the most of having the park to myself. 
Ba Vi National Park is about 60km from Ha  Noi. The entrance is at the foot of a winding road that runs all the way  to the top of the mountain, almost 1300m above sea level. By car or  motorbike, it takes just under an hour to reach the top, but in that  hour the climate changes a lot – and that has always been the  attraction. 
During the French colonial era, which  ended after the Second World War, the cooler mountain climate made Ba Vi  an attractive escape from the heat of the city for French officials and  their families, just as it is among today's expat community.
Like Tam Dao and Da Lat, Ba Vi was chosen  for this reason as the site for colonial villas and retreats for French  officials. However, in comparison to some of the stunning examples of  colonial architecture still visible in Ha Noi today, those in Ba Vi are  dilapidated and lie in ruins, hidden away in the forest that is trying  to reclaim them. 

The bell tower and its intricate brickwork can be seen best from inside the church.
The first of the French ruins can be found  at 400m above sea level, about four kilometres from the national park  office. A sign by the road heralds the entrance to a French Summer Camp,  built for the children of colonial settlers. It lies a short distance  into the woods – just watch out for the creepy crawlies on the way!
Time has overtaken most of the  architecture, and these are the ruins in the worst condition. The roofs  and doors are gone and the stone walls are covered in moss and exposed  to the elements. Some floor tiles and a collapsed chimney are still  visible though, providing a glimpse of what the expat community 100  years ago would have seen too. 
A little further up the mountain, at 600m  above sea level, is the Colonel's Palace. A military establishment,  these walls are over two metres high and half a metre thick. Sub-machine  gun emplacements defend the approach, juxtaposing the children’s summer  camp a little further down the hill. These ruins are a little more well  preserved than the children’s camp, perhaps owing to their military  design. 
However, the most impressive remains lie  another 200m uphill. Following a steep left turn away from the main  road, a bumpy concrete track leads through the woods. The trees get  denser the deeper you go, but don’t be put off yet – it is worth the  wait! 

A cross, its original location unclear, now rests against a wall inside the church.
After a couple of hundred metres the road  leads to a clearing. A church, well preserved from the outside, stands  proudly on the left, surrounded by trees. At dawn, a low mist clings to  the walls. Completing the eerie, horror-movie feel, bats weave in and  out of the hollow windows.
They are obviously not used to being  disturbed so early – one unsuspecting bat collided with my unsuspecting  face, causing a moment of high stress for us both.  
The consequence of passing time is clearer  from the inside. Although the walls and small bell tower are still  standing, the roof is long gone, providing an unobscured view of the sky  above. Trees roots have become intertwined with the walls, and  graffiti, some of it so old that it too has faded, adorn the walls  within reach. 
By the wide double doors at the entrance  is a pile of masonry, perhaps fallen from the arch above. Despite being  in a heap on the floor, the intricate engravings are still clear,  defiant against the passing of time. The floor tiles, on the raised  floor where the altar once would have stood, still show their circular,  uniform design too. 
Resting against the wall is another cross,  though where it was originally isn’t clear. Delicately balanced, it  looks as though it could have been put there yesterday; in reality, it  may have been there for years. There is another cross too, this one cut  into the wall behind the altar, casting a shadow on where the  congregation would have once gathered. 
As for the congregation, though their  reasons for being in Viet Nam would have been very different to the  reasons today's expat community are here, in Ba Vi the reasons are not  too dissimilar – a weekend in the mountains, and a chance to get out of  the capital city.

The military buildings have fared slightly better.
