Paris grew quickly, and passed 800,000 in 1830.[110] Between 1828 and 1860, the city built a horse-drawn omnibus system that was the world's first mass public transit system. It greatly speeded the movement of people inside the city and became a model for other cities.[111] The old Paris street names, carved into stone on walls, were replaced by royal blue metal plates with the street names in white letters, the model still in use today. Fashionable new neighborhoods were built on the right bank around the church of Saint-Vincent-de-Paul, the church of Notre-Dame-de-Lorette, and the Place de l’Europe.
