Nestled in Cork Harbour, Spike Island is a captivating 103-acre island boasting a remarkable history. Once a site of monastic seclusion, its strategic significance transformed it into a fortress and, intriguingly, a prison. Among its historical treasures, the impeccably preserved star-shaped military fortress stands tall, guarding the sole entrance to the harbour, a testament to its enduring legacy.

Every major community in Bhutan has its own dzong, a centre for religious, civic and administrative life, but none is quite as magnificent as Thimphu's Tashichho Dzong. Though this iteration was built in the 18th century, there has been a dzong at this site since 1216, making it one of the most important religious and political places in the country.

Built in 1782, the Grand Palace was the official home of the Thai king for over 150 years. The complex is packed with ornate buildings, gilded spires, and detailed murals — it’s easy to spend a few hours wandering. The highlight is Wat Phra Kaew, the Temple of the Emerald Buddha, which houses Thailand’s most sacred Buddha statue. Arrive early to beat the crowds and heat, and dress respectfully: long trousers and covered shoulders are required, or you won’t get in.
