Unfortunately, World Update XVII made this mod pretty much obsolete.

v2.0 REMOVES the handcrafted versions of Bodiam Castle and Ouse Valley Viaduct so that they don't conflict with the versions from World Update XVII. Only the POIs for Pevensey Castle, Long Man of Wilmington and Litlington White Horse remain.

Do NOT update if for some reason you cannot install World Update XVII.

Bodiam Castle is a 14th-century moated castle near Robertsbridge in East Sussex, England. It was built in 1385 by Sir Edward Dalyngrigge, a former knight of Edward III, with the permission of Richard II, ostensibly to defend the area against French invasion during the Hundred Years' War. Of quadrangular plan, Bodiam Castle has no keep, having its various chambers built around the outer defensive walls and inner courts. Its corners and entrance are marked by towers, and topped by crenellations. Its structure, details and situation in an artificial watery landscape indicate that display was an important aspect of the castle's design as well as defence. It was the home of the Dalyngrigge family and the centre of the manor of Bodiam.

Possession of Bodiam Castle passed through several generations of Dalyngrigges, until their line became extinct, when the castle passed by marriage to the Lewknor family. During the Wars of the Roses, Sir Thomas Lewknor supported the House of Lancaster, and when Richard III of the House of York became king in 1483, a force was despatched to besiege Bodiam Castle. It is unrecorded whether the siege went ahead, but it is thought that Bodiam was surrendered without much resistance. The castle was confiscated, but returned to the Lewknors when Henry VII of the House of Lancaster became king in 1485. Descendants of the Lewknors owned the castle until at least the 16th century.

By the start of the English Civil War in 1641, Bodiam Castle was in the possession of Lord Thanet. He supported the Royalist cause, and sold the castle to help pay fines levied against him by Parliament. The castle was subsequently dismantled, and was left as a picturesque ruin until its purchase by John Fuller in 1829. Under his auspices, the castle was partially restored before being sold to George Cubitt, 1st Baron Ashcombe, and later to Lord Curzon, both of whom undertook further restoration work. The castle is protected as a Grade I listed building and Scheduled Monument. It has been owned by The National Trust since 1925, donated by Lord Curzon on his death, and is open to the public.

NEW in v1.2: The Ouse Valley Viaduct (or the Balcombe Viaduct) carries the London-Brighton Railway Line over the River Ouse in Sussex. It is located to the north of Haywards Heath and the south of Balcombe. Known for its ornate design, the structure has been described as "probably the most elegant viaduct in Britain."

Construction of the Ouse Valley Viaduct commenced by the London & Brighton Railway company in 1839. It was designed by the principal engineer for the line, John Urpeth Rastrick, in association with the architect of the London to Brighton railway, David Mocatta. The viaduct is 96 feet (29 m) high and is carried on 37 semi-circular arches, each of 30 feet (9.1 m), surmounted by balustrades, spanning a total length of 1,480 feet (450 m). Each pier contains a jack arch with a semi-circular soffit, which had the benefit of reducing the number of bricks required. The roughly 11 million bricks required for its construction were mostly shipped up the River Ouse (via Newhaven and Lewes) from the Netherlands. On 12 July 1841, the viaduct was officially opened to train services, although the structure was not fully completed until the following year.

The castle and the viaduct have been recreated manually from various photos and videos from the internet and come with their own POI.

NEW in v1.2: This mod also contains POI markers for landmarks visible in the vanilla game:

Pevensey Castle is a medieval castle and former Roman Saxon Shore fort at Pevensey in the English county of East Sussex. The site is a scheduled monument in the care of English Heritage and is open to visitors. Built around 290 AD and known to the Romans as Anderitum, the fort appears to have been the base for a fleet called the Classis Anderidaensis. The castle was occupied more or less continuously until the 16th century, apart from a possible break in the early 13th century when it was slighted during the First Barons' War. It had been abandoned again by the late 16th century and remained a crumbling, partly overgrown ruin until it was acquired by the state in 1925.
Pevensey Castle was reoccupied between 1940 and 1945, during the Second World War, when it was garrisoned by units from the Home Guard, the British and Canadian armies and the United States Army Air Corps. 

The Long Man of Wilmington or Wilmington Giant is a hill figure on the steep slopes of Windover Hill near Wilmington, East Sussex, England. It is 6 miles (9.7 km) northwest of Eastbourne and 1⁄3 mile (540 m) south of Wilmington. Locally, the figure was once often called the "Green Man". The Long Man is 235 feet (72 m) tall, holds two "staves", and is designed to look in proportion when viewed from below.
Formerly thought to originate in the Iron Age or even the neolithic period, a 2003 archaeological investigation showed that the figure may have been cut in the Early Modern era – the 16th or 17th century AD. From afar the figure appears to have been carved from the underlying chalk; but the modern figure is formed from white-painted breeze blocks and lime mortar.

The Litlington White Horse is a chalk hill figure depicting a horse, situated on Hindover Hill (known locally as High-and-Over) in the South Downs, looking over the River Cuckmere to the west of the village of Litlington and north of East Blatchington in East Sussex, England.
The current horse was cut in 1924 by John T, Ade, Mr Bovis and Eric Hobbis in a single night and stands at 93 ft (28 m) long and 65 ft (20 m) high. A previous horse was cut in either 1838 or 1860 on the same site. Since 1991, the horse has been owned by the National Trust, who, along with local volunteers, regularly clean and maintain the horse.
