The Ho Chi Minh mausoleum grounds are quite large, and landscaped with gardens. In this area, you will find the Ho Chi Minh museum, the mausoleum, Ho Chi Minh's mansion, and Ho Chi Minh's house. You will find old historic pagodas, like the One-Pillar Pagoda. There are numerous vendors here hawking t-shirts and ice cream. It is simply a pleasant place to explore if you have an afternoon in Hanoi.
Unfortunately some parts of the complex are guarded and cordoned off, and it's hard to find your way around. For all of our searching, we never found Ho Chi Minh's house. Luckily, English signs helped us on our way to the One-Pillar Pagoda, a popular spot for Vietnamese to visit. The One-Pillar pagoda, built in the middle of a pond supported by a single pillar, is a beautiful site and we felt caught up in the joy of the other visitors.
Visiting the mauseleum is serious business. You must be appropriately dressed (no hats), and you must leave your camera at the entrance. With our expensive digital SLRs, we weren't going to take any chances and thus missed our chance to see an embalmed Uncle Ho. The architecture of the Mausoleum is quite startling, a square grey building rising incongruously from gorgeous green parkland.
