Excavations around the Devale from time-to-time unearthed building materials, wells, Dutch coins and iron implements of the Middle Ages. North of the old Devalaya at what was known as the old landing place, coins used during the Dutch period in Ceylon, 1554–1765, have been found.

Festivals 
The major festival of the Nawagamuwa Pattini devalaya is the ‘Gonpita Perahera’ held in August each year. This traditional ceremony has been conducted for the past 1500 years in honour of Goddess Pattini, to invoke blessings on the village. The villages rear white bulls exclusively to take part in the annual Perahera Festival.

Restorations
Archeological research has revealed that there are buildings in Nawagamuwa Devalaya premises belonging to both the Kotte Period and the 19th century. The 19th-century restorations and buildings were done by Katuwawala Sri Sumanatissa Thero, the chief priest of the temple during 1813–1928. After constructing the Galkanu devale, Sri Sumanatissa Himi constructed the monks' abode or Sanghavasaya and the Vihare or Pilimage in 1894.

After the restoration of the Devalaya in the 1813–1928 period, the Devalaya has not had any restoration until the New Millennium. In 2016, nearly 100 years later, the Devalaya went through a complete restoration, under the guidance of the Department of Archeology.  The restoration includes, wood-work using the exact type of Jak trees (that yielded honey-sweet fruits) used by original builders, in addition to copper sheet roofing and granite flooring. The restoration cost 30 million rupees to complete. The project was funded by the Nandana Lokuwithana Foundation. With the new renovation project, a life-size marble statue of Goddess Paththini was brought from India to Nawagamuwa. It was unveiled to the public ceremonially on 19 August 2016.
