Besides this _Arsenal_, there are several others in _Berlin_, where they keep Field-Pieces, Iron Cannon, and all that belongs to the Train of Artillery. ’Twas the late Margrave _Philip_[4], Brother to _Frederic_ I. who when he was Great Master of the Ordnance began to put the King’s _Arsenals_ into a good State. But King _Frederic-William_ has finish’d what his said Uncle began, and has put the Artillery on such a footing, that ’tis a question if any _Arsenal_ in _Europe_ is on a better Regulation. A Rampart and a Ditch separate the _Werder_ from the _Dorothy-Stadt_, or new Town, which is for most part inhabited by _French_ Families. It had the Name of _Dorothy-Stadt_ in honour of the Electress _Dorothy_ of _Holstein-Glucksburg_, the second Wife of _Frederic-William_, who with her own Hand planted the first Lime-Tree of the seven great Rows which divide this Ward into two Parts. The middlemost Row, which is the widest, is inclos’d with Ballustrades, and forms a pleasant Grass-Walk for Foot-Passengers. The Walks on each side are pav’d, and serve as a Ring for the Coaches. Nothing is more beneficial and agreeable than taking the Air in this Place, where you may have any thing that can be desir’d in a City. At the end of one of these Walks is a Gate which opens to the Park, the Walks of which being above a League in length, form a fine Point of View. On both sides the Lime-Tree Rows, are Houses, among which the Palace of Madame the Margravine, Dowager[5] to the Margrave _Philip_, Brother to the late King, is one of the best. The late Margrave purchas’d this Palace (which at that time was inconsiderable) of the Wife of _Weiller_ Colonel of the Artillery, who had thrown up his Employments, Wife, Children and all, to go with a Lady of Quality, that was in love with him, to _Vienna_. This Gentlewoman pass’d for a modern _Sappho_, and every body talk’d of her Virtue and good Sense. But being a Slave to the Follies of Love, and asham’d to let them be seen at _Berlin_, where she was counted an Oracle, she resolv’d to quit the Place of her Birth, and engag’d her Lover to leave all and follow her. The Margrave made considerable Augmentations to this House, and render’d it very commodious. The Furniture of the Palace also is rich, and worthy of the Princess who resides in it. Opposite to the Margravine’s Palace is a Building which was formerly call’d the King’s Little Stables, but has been metamorphos’d into Caserns for the Gendarmery; they discover the Magnificence of _Frederic_ I. who caused them to be built. The Apartments that run over the Stables are occupied by the Academy of Painters, and that of Arts and Sciences. Behind the Stables there’s the Observatory, with a great number of Astronomical and Mathematical Instruments, of which there are many of a new Invention.
