A pier is a platform reaching out to sea that can be used as a landing place for ships. If you enjoy sea fishing and don't have a boat, try casting your line from the end of the pier.
Pier has two meanings. The most common is for the platform, often wooden, that extends over water away from shore, so that ships can dock. Many seaside towns have turned their piers into entertainment districts, with games and places to stroll. A pier can also be a pillar that supports a bridge.
