Stonehenge, located on Salisbury Plain, about 10 miles from the medieval city of Salisbury, is Europe's most well-known prehistoric structure. The outstanding Stonehenge visitor centre's exhibitions set the scene for a visit by describing how the megaliths were built between 3000 and 1500 BC and providing information about life at the time through audio-visual experiences and more than 250 ancient items. After exploring the many viewing areas close to these massive stones, visit the genuine reproductions of Neolithic Houses to authenticate the tools and implements of daily Neolithic life as volunteers demonstrate skills from 4,500 years ago.

Due to its popularity, guests must purchase a timed ticket in advance to ensure admission. Although you cannot enter the circle to roam among the rocks during regular operating hours, English Heritage, which manages the site, will give you exclusive access early in the morning or late in the evening.

The Tower of London has served as a prison, castle, treasure vault, observatory, and menagerie. It is also one of London's most popular tourist attractions. There is plenty to see and do at this World Heritage Site, which is frequently cited as England's most significant structure. Visitors can easily spend hours here. The White Tower is the focal point of this fortress along the Thames.

Built in 1078 by William the Conqueror, it is home to outstanding displays, including the Line of Kings, the world's oldest tourist destination. It first opened its doors in 1652 and features a stunning display of royal armor. Other highlights include Yeoman Warder Tours, the Royal Mint, and exhibits and displays related to prisoners and executions. Because the Tower of London spans over 18 acres, there is a lot of research to be done. If you're traveling with children, look into kid-friendly events like "Knights School" and other immersive programs that provide fascinating insights into the castle's history.
