input: For most of the Gaelic period, dwellings and farm buildings were circular with conical thatched roofs (see roundhouse). Square and rectangle-shaped buildings gradually became more common, and by the 14th or 15th century they had replaced round buildings completely. In some areas, buildings were made mostly of stone. In others, they were built of timber, wattle and daub, or a mix of materials. Most ancient and early medieval stone buildings were of dry stone construction. Some buildings would have had glass windows. Among the wealthy, it was common for women to have their own 'apartment' called a grianan (anglicized "greenan") in the sunniest part of the homestead.  The dwellings of freemen and their families were often surrounded by a circular rampart called a "ringfort". There are two main kinds of ringfort. The rath is an earthen ringfort, averaging 30m diameter, with a dry outside ditch. The cathair or caiseal is a stone ringfort. The ringfort would typically have enclosed the family home, small farm buildings or workshops, and animal pens. Most date to the period 500-1000 CE and there is evidence of large-scale ringfort desertion at the end of the first millennium. The remains of between 30,000 and 40,000 lasted into the 19th century to be mapped by Ordnance Survey Ireland. Another kind of native dwelling was the crannog, which were roundhouses built on artificial islands in lakes.  There were very few nucleated settlements in Gaelic areas. However, after the 5th century some monasteries became the heart of small "monastic towns". By the 10th century the Norse-Gaelic ports of Dublin, Wexford, Cork and Limerick had grown into substantial settlements. It was at this time, perhaps as a response to Viking raids, that many of the Irish round towers were built.  In the fifty years before the Norman invasion, the term "castle" (Old Irish: caistel/caislen) appears in Gaelic writings, although there are no surviving examples of pre-Norman castles. After the invasion, the Normans built motte-and-bailey castles in the areas they occupied, some of which were converted from ringforts. By 1300 "some mottes, especially in frontier areas, had almost certainly been built by the Gaelic Irish in imitation". The Normans gradually replaced wooden motte-and-baileys with stone castles and tower houses. Tower houses are free-standing multi-storey stone towers usually surrounded by a wall (see bawn) and ancillary buildings. Gaelic families had begun to build their own tower houses by the 15th century. As many as 7000 may have been built, but they were rare in areas with little Norman settlement or contact. They are concentrated in counties Limerick and Clare but are lacking in Ulster, except the area around Strangford Lough.  In Gaelic law, a 'sanctuary' called a maighin digona surrounded each person's dwelling. The maighin digona's size varied according to the owner's rank. In the case of a boaire it stretched as far as he, while sitting at his house, could cast a cnairsech (variously described as a spear or sledgehammer). The owner of a maighin digona could offer its protection to someone fleeing from pursuers, who would then have to bring that person to justice by lawful means.

input: In addition to winning the Emmy for The Joan Rivers Show, Rivers starred in the made-for-television comedy How to Murder a Millionaire, which premiered in May 1990 on CBS. In the film, co-starring Alex Rocco and Telma Hopkins, she took on the role of a Beverly Hills matron possessed with the idea her husband is trying to kill her. Also in 1990, she started to design jewelry, clothing and beauty products for the shopping channel QVC. On this professional endeavor, Rivers said: "In those days, only dead celebrities went on [QVC]. My career was over. I had bills to pay. [...] It also intrigued me at the beginning". The sales of Rivers' products exceed $1 billion by 2014, making her one of the network's top sellers. In 1991, she wrote her next book, Still Talking, which described the cancellation of her late-night show and her husband's suicide. Until 1993, she received five addicional Emmy nominations for her daytime talk-show The Joan Rivers Show -- two for Outstanding Writing - Special Class and three for Outstanding Talk Show Host.  In 1994, Rivers and daughter Melissa first hosted the E! Entertainment Television pre-awards show for the Golden Globe Awards, and beginning in 1995, E!'s annual Academy Awards pre-awards show as well. Rivers and her daughter quickly became credited for revolutionizing the red carpet as a space to showcase designers' work and celebrity interactions. "Joan and Melissa were the first people who came out and made it more of a true conversation between star and reporter", E!'s Senior Vice President of production, Gary Snegaroff, remarked to Vanity Fair. "They asked about what [actresses] were wearing because that's what the magazines would cover after the fact, and turned it into a candid conversation on the carpet where anything could happen". Rivers and Melissa, at the time, both portrayed themselves in the made-for-television drama Tears and Laughter: The Joan and Melissa Rivers Story, which chronicled the aftermath of Rosenburg's suicide. It aired on NBC on May 15, 1994. The next year, she wrote her book Jewelry by Joan Rivers.  Influenced by the stand-up comedy of Lenny Bruce, Rivers co-wrote and starred in a play about Bruce's mother Sally Marr, who was also a stand-up comic and influenced her son's development as a comic. After 27 previews, Sally Marr ... and Her Escorts, a play "suggested by the life of Sally Marr" ran on Broadway for 50 performances in May and June 1994. The production received mixed reviews, but her performance was applauded by critics. The Chicago Sun Times found Rivers to be "compelling" as an actress while The New York Times wrote: "[...] [S]he is exuberant, fearless and inexhaustible. If you admire performers for taking risks, then you can't help but applaud her efforts". Rivers was nominated for a Drama Desk Award as Outstanding Actress in a Play and a Tony Award for Best Actress in a Play for playing Marr. Beginning in 1997, Rivers hosted her own radio show on WOR in New York City, and wrote three self-help books: Bouncing Back: I've Survived Everything ... and I Mean Everything ... and You Can Too! in 1997, From Mother to Daughter: Thoughts and Advice on Life, Love and Marriage in 1998, and Don't Count the Candles: Just Keep the Fire Lit!, in 1999.
