The Grand Palace

The Grand Palace

Historical landmark
7 kms
The Grand Palace has an area of 218,400 sq. metres and is surrounded by walls built in 1782. The length of the four walls is 1,900 metres. Within these walls are situated government offices and the Chapel Royal of the Emerald Buddha besides the royal residences. When Siam restored law and order after the fall of Ayutthaya the monarch lived in Thonburi on the west side of the river. Rama I, on ascending the throne, moved the centre of administration to this side of the Chao Phraya; and, after erecting public monuments such as fortifications and monasteries, built a palace to serve not only as his residence but also his offices--the various ministries, only one of which remains in the palace walls.

Jim Thompson House

Jim Thompson House

Museum
2 kms
The Jim Thompson House is the home of James H.W. Thompson, a self-made American entrepreneur who was the founder of the world renowned Jim Thompson Thai Silk Company. Thompson's achievements during his 25 year stay in the Kingdom of Thailand have won him much fame as the "Legendary American of Thailand". For his contribution to the development of the Thai Silk industry, Jim Thompson was awarded the Order of the White Elephant, a decoration bestowed upon foreigners for having rendered exceptional service to Thailand. Thompson's success story in Thailand has become one of the most popular postwar legends of Asia. In 1967, Jim Thompson went on holiday with friends to the Cameron Highlands in Malaysia. There he set out for a walk in the surrounding jungle but never returned. Thus began the Jim Thompson legend. Since his disappearance in 1967, little has changed in the home that was the 'talk of the town' and the 'city's most celebrated social center'. Even today, the charming Thai style house continues to be a key stop for visitors to Bangkok. The house consists of a complex of six traditional Thai-style houses, teak structures that were purchased from several owners and brought to the present location from various parts of Thailand. Construction of the Thai house was completed in 1959.

On Purpose Adventures
On Purpose Adventures
Multi-city
Crossed arms. Poked out bottom lips. Eye rolls. Sighs of displeasure. Mention team building, and you might get these reactions. The thought of another ropes course, forced togetherness or (gasp!) trust falls while keeping your already busy team from their work can create more stress than staying at the workplace. But not with On Purpose Adventures. Your group may need team building (focused on skill development/enhancement) or team bonding (focused on relationship-minded activities) or a combination of both. But whatever the activity, it needs to be facilitated WITH purpose and ON purpose. Most team building programs don’t tie the experience into real-world, job-related application. But ours does. On Purpose delivers team building and bonding with a purpose. Our programs are structured around the way your team operates, and can be tailored to fit your specific challenges and goals. Your team will engage in collaborative activities that build communication, cohesiveness, and enhance skills like collective problem solving, while having fun together. Team building and bonding with On Purpose Adventures brings your team members together in exciting, driven, purposeful activities that make a big impression and generate a genuine team response, keeping them productive and engaged. Skill enhancement happens in a real-life relatable structure, so your takeaways aren’t easily forgotten or lost as soon as the fun ends. Let us help you strengthen your team - on purpose.
