In the heart of Vientiane city, there is one really stand out monument. The name is Patuxay which translate to victory gate. The monument is located inside a quite big and nice park (Patuxay Park.) The park sometimes get a bit too crowded especially on weekend evening. So one needs to be a little bit patient to get a scene with less people in the frame.
There is no entrance fee to get inside the park, but there is a small entrance fee if you want to go inside the monument building. The monument is closed at 6.00PM but the park stays open all the time.
Once you enters the monument, you have the access to use the stairways to go to the roof top. You can view a good portion of Vientiane city from there.
For a poor traveler/photographer wannabe like me, Patuxay park is a really nice place to visit. Its almost free and got some nice views that can turn to some decent photographs.
Here some more photo I took at Patuxay (the photos looks shoft in some browsers, but if you click on it, you can view the bigger and sharper photo):
