The Royal Botanic Garden Edinburgh (RBGE) is a scientific centre for the study of plants, their diversity and conservation, as well as a popular tourist attraction. Originally founded in 1670 as a physic garden to grow medicinal plants, today it occupies four sites across Scotland — Edinburgh, Dawyck, Logan and Benmore — each with its own specialist collection. The RBGE's living collection consists of more than 13,302 plant species, whilst the herbarium contains in excess of 3 million preserved specimens.
The Edinburgh botanic garden was founded in 1670 at St. Anne's Yard, near Holyrood Palace, by Dr. Robert Sibbald and Dr. Andrew Balfour. It is the second oldest botanic garden in Britain after Oxford's. The plant collection used as the basis of the garden was the private collection of Sir Patrick Murray, 2nd Lord Elibank, moved from his home at Livingston Peel in 1672 following his death in September 1671. This site proved too small, and in 1676 grounds belonging to Trinity Hospital were leased by Balfour from the City Council: this second garden was sited just to the east of the Nor Loch, down from the High Street. The site was subsequently occupied by tracks of the North British Railway, and a plaque at platform 11 of the Waverley railway station marks its location.
In 1763, the garden's collections were moved away from the city's pollution to a larger 'Physick Garden' on the west side of Leith Walk. In the early 1820s under the direction of the botanist Daniel Ellis and several others, the garden moved west to its present location as the 'New Botanic Garden' adjacent to Inverleith Row, and the Leith Walk site was built over as Gayfield Square and surrounding development. The Temperate Palm House, which remains the tallest in Britain to the present day, was built in 1858. A small section of the Leith Walk garden and planting still exists in the gardens in Hopetoun Crescent.
In 1877 the City acquired Inverleith House from the Fettes Trust and added it to the existing gardens, opening the remodelled grounds to the public in 1881. The botanic garden at Benmore became the first Regional Garden of the RBGE in 1929. It was followed by the gardens at Logan and Dawyck in 1969 and 1978.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
