My longest contribution to the city wiki of Dresden features its twin city Wroclaw/Breslau.

My Wikipedia user page links to some of my major contributions. Among them is an article on my hometown Bischofswerda (shortened):

Bischofswerda is located 33 km to the east of Dresden at the edge of the Upper Lusatian mountain country. The town is known as the "Gateway to Upper Lusatia", "Tor zur Oberlausitz" in German. It is located in the district of Bautzen. The town is 18 km west of Bautzen itself. The river Wesenitz flows through Bischofswerda.

The first documentary evidence of the existence of the town dates from 1227. Nominally it was founded by the Bishops of Meissen, though it may have existed before that point. In 1288 city walls were constructed. The first mention of Bischofswerda as a city is in a document dating from 1361. The town remained under the authority of the Bishops of Meissen until 1559 when power was transferred to Augustus, Elector of Saxony, who introduced Protestantism. The city arms are based on a 14th-century seal and consist of two crossed bishop's croziers and four stars. Like many late medieval towns, Bischofswerda suffered from periodic fires that damaged the town. Fires are recorded in 1429, 1469, 1528, 1583, 1596, 1641, 1671 and 1813. The last fire was the worst. During the War of the Sixth Coalition, Napoleonic forces had occupied Bischofswerda when a fire broke out within the town walls on 12 May 1813, destroying most of the medieval town. However the town was rebuilt on an order of Frederick Augustus I of Saxony in a manner closely following the earlier layout, and this remains to this day.

Until the German reunification in 1990, Bischofswerda was a significant industrial location. In Bischofswerda, the company Fortschritt produced agricultural machines. This manufacture as well as the glass fabrication had to be closed in the meanwhile. The textile industry had a centuries-long tradition in the town, but also ended in 2012.

Among the most impressive buildings are the town hall and the Christuskirche. Both are examples of neo-classical architecture and were designed by Gottlob Friedrich Thormeyer. The town hall (Rathaus) was constructed in 1818, just off the Altmarkt, the centre of the town. The entrance to the Christuskirche is decorated by a mosaic by Josef Goller. In the interior one can find a painting by Osmar Schindler, who grew up in the town. The Catholic church is named after Saint Benno of Meissen, who is said to have founded Bischofswerda in the 11th century. ... read more in the Wikibook (PDF).

I visited this beautiful location on Sicily/Italy in December 2001. My hotel, situated at Corso Umberto, let me look up to Mount Etna from breakfast room, the other window let me look down to the sea - what a contrast! This highest of all active European vulcanos was rarely to be seen that time, unfortunately, because of rainy weather. Corso Umberto belongs to the Roman "Via Valeria", connecting Messina and Catania at east coast. Without car, it appeared to be difficult to organise trips personally. Organised journeys by bus were cancelled without exception, because of lack of interest (only few tourists being there). But there were two alternatives: going by foot uphill and downhill (same level nearly not possible), or to use public bus. My recommendations: Greek theatre, gardens of Miss Florence Trevelyan (many exotic trees) in Taormina, going uphill to Castelmola (531 m) and Castello Saraceno (398 m) by foot, downhill to the marvellous island "Isola Bella" and to the sea resort Spisone. Really nice, but a little bit demanding for physical constitution. Public bus is a really cheap way of transportation there: Giardini-Naxos, Messina, Catania, old Greek Syracusa, all of them reachable for little money, in short time and by trips offering marvellous views. ...more photos 2001

I got my first impression from the British Isles when flying in 1991 to Manchester (to attend a conference in Springfields) via London. When approaching Heathrow, Windsor was directly below. In 1994, I spent a holiday week, living in Knightsbridge near Hyde Park, beautiful. Besides the many MUSTs (Buckingham Palace, Big Ben, Trafalgar Square, British Museum, Tower, again Windsor, Westminster Abbey, St. Paul's, Picadilly Circus, Madame Tussaud's) I remember one day when going (by foot) through the Docklands to Greenwich with its observatory, museums and Cutty Sark sailing ship. Excursions led to Oxford (by train) and by bus to Leeds Castle, Canterbury, Dover. Another day, visiting botanic Kew Gardens was really worth time. The same year, I had to/could attend as substitute a conference in York. Afterwards I spent - to reduce flight costs - the weekend in London again. Otherwise I had missed the flight. I experienced a strike for the first time, when sitting in the train towards London. The hotel near Picadilly was interesting too. They tried to have not got my (discount) in advance booking, of course offering generously another room, and during the night there were at least 5 wrong fire alarms. Besides, I made excursions of one day each by train to Brighton and Cambridge. An extended business trip to the South Bank in 1996 , that time approaching Heathrow parallely river Thames vis-a-vis Houses of Parliament, allowed me to make a weekend excursion to Salisbury, Stonehenge and Bath. And it was for the first time that I had to escape a railway station because of a bombing alarm. ... read more in German (PDF) or play English history.
