Easton's Bible Dictionary (1897)
New city, a town in Thrace at which Paul first landed in Europe (Acts 16:11). It was the sea-port of the inland town of Philippi, which was distant about 10 miles. From this port Paul embarked on his last journey to Jerusalem (Acts 20:6). It is identified with the modern Turco-Grecian Kavalla.
Smith's Bible Dictionary (1863)
(new city) is the place in northern Greece where Paul and his associates first landed in Europe. (Acts 16:11) where, no doubt, he landed also on his second visit to Macedonia, (Acts 20:1) and whence certainly he embarked on his last journey through that province to Troas and Jerusalem. (Acts 20:6) Philippi being an inland town, Neapolis was evidently the port, and is represented by the present Kavalla . (Kavalla is a city of 5000 or 6000 inhabitants, Greeks and Turks.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
NEAP'OLIS (new city), a place in Northern Greece where Paul first landed in Europe, and where he probably landed on his second visit. Acts 16:11; 20:1, and whence he embarked on his last journey to Jerusalem. Acts 20:6. It was on a rocky eminence, the most conspicuous object being a temple of Diana, which crowned the top of the hill. The great Roman road Via Egnatia, from Macedonia to Thrace, passed through Neapolis, which was 8 or 10 miles from Philippi. It is now a Turko-Grecian town of 5000 or 6000 population, and called Kavalla; it has numerous ruins.
Another site has been proposed (Eski) for Neapolis, but the arguments for it are unsatisfactory. The Roman name of Shechem was also Neapolis, but it is not so named in Scripture.
