The Botanic Gardens of Belfast opened in 1828 as the private Royal Belfast Botanical Gardens. It continued as a private park for many years, only opening to members of the public on Sundays prior to 1895. Then it became a public park in 1895 when the Belfast Corporation bought the gardens from the Belfast Botanical and Horticultural Society.
Occupying 28 acres (110,000 m2) of south Belfast, the gardens are popular with office workers, students and tourists. The gardens' most notable feature is the Palm House conservatory. It was completed in 1840. It is one of the earliest examples of a curvilinear cast iron glasshouses in the world. The Palm House consists of two wings, the cool wing and the tropical wing. Lanyon altered his original plans to increase the height of the latter wing's dome, allowing for much taller plants. In the past these have included an 11 metre tall globe spear lily. The lily, which is native to Australia, finally bloomed in 2005 after a 23-year wait. The Palm House also features a 400-year-old Xanthorrhoea.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
