From the 1730s, Brighton entered its second phase of development—one which brought a rapid improvement in its fortunes. The contemporary fad for drinking and bathing in seawater as a purported cure for illnesses was enthusiastically encouraged by Dr Richard Russell from nearby Lewes. He sent many patients to "take the cure" in the sea at Brighton, published a popular treatise on the subject, and moved to the town soon afterwards (the Royal Albion, one of Brighton's early hotels, occupies the site of his house). Others were already visiting the town for recreational purposes before Russell became famous, and his actions coincided with other developments which made Brighton more attractive to visitors. From the 1760s it was a boarding point for boats travelling to France; road transport to London was improved when the main road via Crawley was turnpiked in 1770; and spas and indoor baths were opened by other entrepreneurial physicians such as Sake Dean Mahomed and Anthony Relhan (who also wrote the town's first guidebook).
